wifi: ath12k: dp_mon: Fix unsigned comparison with less than zero 



The return value from the call to idr_alloc() is int.
However, the return value is being assigned to an unsigned
int variable 'buf_id', so making 'buf_id' an int.

Eliminate the following warning:
./drivers/net/wireless/ath/ath12k/dp_mon.c:1300:15-21: WARNING: Unsigned expression compared with zero: buf_id < 0
