zvol: Temporally disable blk-mq
There was a report of zvol data loss (#15351) after enabling blk-mq on a
zvol backed with 16k physical block sized disks.  Out of an abundance of
caution, do not allow the user to enable blk-mq until we can look into
the issue.

Note that blk-mq was not enabled by default on zvols.  It was always
opt-in via the zvol_use_blk_mq module parameter.
