qcacmn: Disable PN Error handling in the REO

Disable PN error handling in REO Queue descriptor setup.
This is different from pn check enable.
When PN error handling is enabled, if a PN check fails
REO queue descriptor sets pn_error_detected,
All the subsequent packets will  be exceptioned with REO error code 13
till SW resets the pn_error_detected.

SW is not doing any special handling when PN error handling is enabled
Hence disabling flag in setup time instead of resetting/updating
reo queue descriptor as update is an uncessary overhead.
