The mes_v11_0_reset_hw_queue and mes_v12_0_reset_hw_queue functions were
using the wrong union type (MESAPI__REMOVE_QUEUE) when getting the offset
for api_status. Since these functions handle queue reset operations, they
should use MESAPI__RESET union instead.
This fixes the polling of API status during hardware queue reset operations
in the MES for both v11 and v12 versions.

This commit introduces a NULL pointer check for
mpc->funcs->program_lut_mode in the dcn401_populate_mcm_luts function.
The previous implementation directly called program_lut_mode without
validating its existence, which could lead to a NULL pointer
dereference.
With this change, the function is now only invoked if
mpc->funcs->program_lut_mode is not NULL
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn401/dcn401_hwseq.c:720 dcn401_populate_mcm_luts()

GCC really does not want to consider NULL (or near-NULL) addresses as
valid, so calculations based off of NULL end up getting range-tracked into
being an offset wthin a 0 byte array. It gets especially mad about this:
if (vbios_str == NULL)
vbios_str += sizeof(BIOS_ATOM_PREFIX) - 1;
...
if (vbios_str != NULL && *vbios_str == 0)
vbios_str++;
It sees this as being "sizeof(BIOS_ATOM_PREFIX) - 1" byte offset from
NULL, when building with -Warray-bounds (and the coming
-fdiagnostic-details flag):
In function 'atom_get_vbios_pn',
inlined from 'amdgpu_atom_parse' at drivers/gpu/drm/amd/amdgpu/atom.c:1553:2:
drivers/gpu/drm/amd/amdgpu/atom.c:1447:34: error: array subscript 0 is outside array bounds of 'unsigned char[0]' [-Werror=array-bounds=]

In function 'amdgpu_atom_parse':
cc1: note: source object is likely at address zero
As there isn't a sane way to convince it otherwise, hide vbios_str from
GCC's optimizer to avoid the warning so we can get closer to enabling
-Warray-bounds globally.

The domain pointer is not used, but the irq_data pointer is required to be

Add the missing NULL pointer check to ensure there is a non-NULL irq_data
