[PATCH] apparmor: remove unused variable

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

The local 'sock' variable has become unused after a change to the
aa_sock_file_perm() calling conventions:

security/apparmor/file.c: In function '__file_sock_perm':
security/apparmor/file.c:544:24: error: unused variable 'sock' [-Werror=unused-variable]
  544 |         struct socket *sock = (struct socket *) file->private_data;

Remove it here.

Fixes: c05e705812d1 ("apparmor: add fine grained af_unix mediation")
