net: dsa: sja1105: fix check on while loop exit

The while-loop exit condition check is not correct; the
loop should continue if the returns from the function calls are
negative or the CRC status returns are invalid.  Currently it
is ignoring the returns from the function calls.  Fix this by
removing the status return checks and only break from the loop
at the very end when we know that all the success condtions have
been met.

Kudos to Dan Carpenter for describing the correct fix and
Vladimir Oltean for noting the change to the check on the number
of retries.
