wifi: ath11k: Fix unexpected return buffer manager error for WCN6750/WCN6855

The following error messages were encountered while parsing fragmented RX
packets for WCN6750/WCN6855:

ath11k 17a10040.wifi: invalid return buffer manager 4

This issue arose due to a hardcoded check for HAL_RX_BUF_RBM_SW3_BM
introduced in 'commit 71c748b5e01e ("ath11k: Fix unexpected return buffer
manager error for QCA6390")'

For WCN6750 and WCN6855, the return buffer manager ID should be
HAL_RX_BUF_RBM_SW1_BM. The incorrect conditional check caused fragmented
packets to be dropped, resulting in the above error log.

Fix this by adding a check for HAL_RX_BUF_RBM_SW1_BM.

Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.2.0.c2-00258-QCAMSLSWPL-1
Tested-on: WCN6855 hw2.1 WLAN.HSP.1.1-04479-QCAHSPSWPL_V1_V2_SILICONZ_IOE-1
