misc: mei: fix stalled read



This bug caused severe connectivity issue in the LMS application
(LMS is described in  Documentation/misc-devices/mei/mei.txt)

The bug was introduced in patch:
commit 1ccb7b62
staging/mei: propagate error codes up in the write flow

The patch has reverted the return value logic of some fo function but
the conditional in _mei_irq_thread_read function was not swapped
making read always entering the error path
