[PATCH ath-next 2/2] wifi: ath12k: Extend BA buffer size to 1024 for EHT capable links

[Rameshkumar Sundaram]

From: Paulson Raja L <lraja at qti.qualcomm.com>

IEEE 802.11be (EHT) extends the maximum BA buffer size from 256 MPDUs
(HE) to 1024 MPDUs. EHT-capable links are currently limited to the
HE maximum of 256.

Add WMI_BA_MODE_BUFFER_SIZE_1024 and select the buffer size based on
the negotiated mode: 1024 for EHT-capable links, 256 for HE-only.
Also include the return code when reporting BA mode configuration
failure to aid debugging.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01243-QCAHKSWPL_SILICONZ-1
