[PATCH] io_uring: remove redundant variable pointer nxt and io_wq_assign_next call

[Colin King <colin.king@canonical.com>]

From: Colin Ian King <colin.king@canonical.com>

An earlier commit "io_uring: remove @nxt from handlers" removed the
setting of pointer nxt and now it is always null, hence the non-null
check and call to io_wq_assign_next is redundant and can be removed.

Addresses-Coverity: ("'Constant' variable guard")
