apparmor: Remove unused variable 'sock' in __file_sock_perm()
When CONFIG_SECURITY_APPARMOR_DEBUG_ASSERTS is disabled, there is a
warning that sock is unused:
security/apparmor/file.c: In function '__file_sock_perm':
security/apparmor/file.c:544:24: warning: unused variable 'sock' [-Wunused-variable]
544 | struct socket *sock = (struct socket *) file->private_data;
| ^~~~
sock was moved into aa_sock_file_perm(), where the same check is
present, so remove sock and the assertion from __file_sock_perm() to fix
the warning.
