[PATCH] userfaultfd: remove redundant pointer uwq

[PATCH] userfaultfd: remove redundant pointer uwq

[Colin King]

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

Pointer uwq is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'uwq' set but not used [-Wunused-but-set-variable]
