Up till now, the reorder buffer uses standard spec based comparison when comparing the buffer status to NSSN. This indeed works for the regular case, since we shouldn't cross the 2048 boundary without getting a frame release notification. However, this is problematic due to packet filtering that may be performed by the FW while we are in d0i3. Theoretically we may filter over 2048 packets, and then the check of the NSSN will get incorrect. Change the comparison to always trust nssn unless it is 64 or less frames behind the head - which might happen due to a timeout. This new comparison is to be used only when comparing reorder buffer head with nssn, and not when comparing the packet SN to nssn or reorder buffer head. Put this in a separate commit as the logic is a bit tricky and stands for its own commit message.
