qlcnic: avoid using reset_devices as it may become obsolete. 

In kdump environment do not depend upon reset_devices parameter
to reset the pci function as this parameter may become obsolete.
Instead use an adapter specific mechanism to determine if the pci
function needs to be reset.

Per function refcount is maintained in driver, which is set in probe
and reset in remove handler of adapter. If the probe detects the count
as non zero then reset the function.
