Revert "ath11k: mesh: add support for 256 bitmap in blockack frames in 11ax"

This reverts commit 743b9065fe6348a5f8f5ce04869ce2d701e5e1bc.

The original commit breaks the 256 bitmap in blockack frames in AP
mode. After reverting the commit the feature works again in both AP and
mesh modes

Tested-on: IPQ8074 hw2.0 PCI WLAN.HK.2.6.0.1-00786-QCAHKSWPL_SILICONZ-1

Fixes: 743b9065fe63 ("ath11k: mesh: add support for 256 bitmap in blockack frames in 11ax")
