nvmet: add a helper function for cqid checking

Browse source

This patch adds a new helper function nvmet_check_io_cqid(). It is to be
used when parsing host commands for IO CQ creation/deletion and IO SQ
creation to ensure that the specified IO completion queue identifier
(CQID) is not 0 (Admin queue ID). This is a check that already occurs in
the nvmet_execute_x() functions prior to nvmet_check_cqid.

With the addition of this helper function, the CQ ID checks in the
nvmet_execute_x() function can be removed, and instead simply call
nvmet_check_io_cqid() in place of nvmet_check_cqid().
