qcacmn: Handle all the REO error codes

For certain wlan chips, eg WCN7850, all the REO error
codes are routed to the APPS core and none are handled
by the firmware.

Add support to handle all the REO errors. Currently for
all the newly handled REO errors, the packet is dropped
and the corresponding link descriptor is returned to the WBM.
