e1000e: remove failed request for sw/fw/hw flag

Browse source 
When the driver fails to acquire the control flag used to serialize
NVM and PHY accesses between the driver, firmware and hardware, remove the
request for the flag otherwise the hardware might grant the flag when it
becomes available but the driver will not release the flag.  This could
cause the firmware to prevent the driver getting the flag for all future
attempts.
