nvmet-fc: Annotate struct nvmet_fc_tgt_queue with __counted_by
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct
nvmet_fc_tgt_queue. Additionally, since the element count member must
be set before accessing the annotated flexible array member, move its
initialization earlier.
