[PATCH 2/9] fs: fix empty-body warning in posix_acl.c

[Randy Dunlap <rdunlap@xxxxxxxxxxxxx>]

Fix gcc empty-body warning when -Wextra is used:

../fs/posix_acl.c: In function ‘get_acl’:
../fs/posix_acl.c:127:22: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]
   /* fall through */ ;
                      ^
