Subject: [PATCH] block: remove useless BUG_ON() in blk_mq_put_tag()
Git-commit: ff47dbd18b8db251fe1fd013a8fa067d381ecd5b
Patch-mainline: v5.19-rc1
References: jsc#PED-1183

Since the if condition in blk_mq_put_tag() checks that the tag to put is
not a reserved one, the BUG_ON() check in the else branch checking if
the tag is indeed a reserved one is useless. Remove it.
