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.

nvme-fc: do not reference lsrsp after failure

The lsrsp object is maintained by the LLDD. The lifetime of the lsrsp
object is implicit. Because there is no explicit cleanup/free call into
the LLDD, it is not safe to assume after xml_rsp_fails, that the lsrsp
is still valid. The LLDD could have freed the object already.

With the recent changes how fcloop tracks the resources, this is the
case. Thus don't access lsrsp after xml_rsp_fails.
