qcacmn: Set the packet start offset correctly for monitor mode

Browse Source 
The packet start offset configuration is common
for both mission mode and monitor mode. Hence if
the packet_header tlv is not subscribed for the
regular mission mode, the packet start offset for
monitor mode also gets affected, where packet_header
is subscribed.

This causes a loss of 128 bytes in the packets
captured in monitor mode.
Fix this issue, by setting the packet start offset
based on the driver operation mode.
