cifs: remove the retry in cifs_poxis_lock_set

/*

 * Set the byte-range lock (posix style). Returns:

 * 1) 0, if we set the lock and don't need to request to the server;

 * 2) 1, if we need to request to the server;

 * 3) <0, if the error occurs while setting the lock.

 * 1) <0, if the error occurs while setting the lock;

 * 2) 0, if we set the lock and don't need to request to the server;

 * 3) FILE_LOCK_DEFERRED, if we will wait for some other file_lock;

 * 4) FILE_LOCK_DEFERRED + 1, if we need to request to the server.
