Optimize audit_free_names() by quitting early if the name list is empty.
This eliminates the need to acquire and release the fs_struct spinlock

Why would path_put() go anywhere need fs_struct spinlock???
path_put() is defined in include/linux/fs_struct.h. It calls
read_seq{un}lock_excl(&fs->seq) which, in turn, acquires the releases
the spinlock underneath the seqlock_t.
