e1000e: do not ever sleep in interrupt context

e1000e was apparently calling two functions that attempted to reserve
the SWFLAG bit for exclusive (to hardware and firmware) access to
the PHY and NVM (aka eeprom).  These accesses could possibly call
msleep to wait for the resource which is not allowed from interrupt
context.
