Shorten up the delays in the init task, allowing the VF driver to
initialize faster. This aids performance in load/unload tests and
mitigates DMAR errors in VF enable/disable tests with absurdly short
delays. In the real world, the VF driver will come up more quickly.
The original values were set conservatively based on what we expected
from the firmware in terms of performance. Now that the driver is in use
and we know how well firmware responds to our requests, we can shorten
these delays.

Using VFGEN_RSTAT to detect a VF reset is an endeavor that is fraught
with peril. It's entirely too easy to miss a reset because none of the
bits are sticky. By the time the VF driver reads the register, the reset
may have been processed and cleaned up by the PF driver, leaving the
register in the same state that it was before the reset.
Instead, detect a reset with the VF_ARQLEN register. When the VF is
reset, the enable bit in this register is cleared, and it stays cleared
until the VF driver processes the reset and re-enables the admin queue.
Because we now deal with multiple registers in the reset and watchdog
tasks, rename the rstat_val variable to reg_val.
