[PATCH] st_getattr: do not expect server to return rdattr_error

[Tigran Mkrtchyan <tigran.mkrtchyan@xxxxxxx>]

rfc7530:
   5.8.1.12.  Attribute 11: rdattr_error

     Error returned from an attempt to retrieve attributes during a
     READDIR operation.

IOW, we do not expect rdattr_error to be returned in reply to regular
GETATTR operation.
