mds: repeat dir->is_frozen in rdlock_path_xlock_dentry

Because traverse_to_auth_dir() in the rdlock_path_xlock_dentry() call dir->is_frozen, as "traverse_to_auth_dir ---> validate_dentry_dir() ---> dir->is_frozen()", so this is repeated to judge "dir->is_frozen()" in "rdlock_path_xlock_dentry()". Signed-off-by: huanwen ren <[email protected]>
