iwlwifi: dvm: run INIT firmware again upon .start()
commit 9c8928f5176766bec79f272bd47b7124e11cccbd upstream.
The assumption before this patch was that we don't need to
run again the INIT firmware after the system booted. The
INIT firmware runs calibrations which impact the physical
layer's behavior.
Users reported that it may be helpful to run these
calibrations again every time the interface is brought up.
The penatly is minimal, since the calibrations run fast.
This fixes:
