ath11k: change return buffer manager for QCA6390
QCA6390 firmware uses HAL_RX_BUF_RBM_SW1_BM, not HAL_RX_BUF_RBM_SW3_BM. This is
needed to fix a case where an A-MSDU has an unexpected LLC/SNAP header in the
first subframe (CVE-2020-24588).
Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
