Jan Höppner 8542885bf5 s390/dasd: Simplify code in format logic
Currently, dasd_format is calling the format logic of a DASD discipline
with PAV enabled. If that fails with an error code of -EAGAIN the value
of retries is decremented and the discipline function is called with PAV
turned off.

The loop is supposed to try this up to 255 times until success. However,
-EAGAIN can only occur once here and therefore the loop will never reach
the 255 retries.

So, replace the unnecessarily complicated loop logic and simply try again
without PAV enabled in case of an -EAGAIN error.
