nvme: fix multiple spelling and grammar issues in host drivers

This commit fixes several typos and grammatical issues across various
nvme host driver files:

 - correct "glace" to "glance" in a comment in apple.c
 - fix "Idependent" to "Independent" in core.c
 - change "unsucceesful" to "unsuccessful", "they blk-mq" to "the blk-mq",
 - fix "terminaed" to "terminated" and other grammar in fc.c
 - update "O's" to "0's" to clarify meaning in nvme.h
 - fix a function name reference in a comment in zns.c:
   *_transter_len() -> *_transfer_len().
 - fix sysfs_emit() output format in pci.c (replace x%08x with 0x%08x)

These changes improve the code readability and documentation consistency
across the NVMe driver.
