iwlwifi: implement remain-on-channel

For device supporting PAN/P2P, use the PAN
context to implement the remain-on-channel
operation using device offloads so that the
filters in the device will be programmed
correctly -- otherwise we cannot receive
any probe request frames during off-channel
periods.
