watchdog: ziirave_wdt: Check packet length only once

Browse source

We don't need to check for packet length more than once, so drop the
extra check in ziirave_firm_upload(). While at it move the check at
the very start of __ziirave_firm_write_pkt(), as to not waste any time
preparing a packet we'll never use.
