[PATCH ath-next v3] wifi: ath12k: Fix double budget decrement while reaping monitor ring

[P Praneesh]

Currently, the budget for monitor ring is reduced during each ring entry
reaping and again when the end reason is HAL_MON_END_OF_PPDU, leading to
inefficient budget use. The below mentioned commit intended to decrement
the budget only for HAL_MON_END_OF_PPDU but did not remove the other
decrement. Fix this by eliminating the budget decrement for each ring entry
reaping, ensuring the driver always reaps one full PPDU worth of entries
from the monitor destination ring.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
