ice: Check if VF is disabled for Opcode and other operations

Browse source

This patch adds code to check if PF or VF is disabled before honoring
mailbox message to configure VF - If it is disabled, and opcode is for
resetting VF, the PF driver simply tell VF that all is set. In addition,
if reset is ongoing, and Admin intend to configure VF on the host, we can
poll the VF enabling bit to make sure it is ready before continue - If
after ~250 milliseconds, VF is not in active state, we can bail out with
invalid error.
