BA CAM entries are global resource of hardware, so move the bitmap and
instances to rtw89_cam_info, and then use link list from rtw89_sta to
these instances.
To check the allocation, add ba_cam to debugfs:
map:
mac_id: 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
addr_cam: 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
bssid_cam: 01 00 00 00 00 00 00 00
sec_cam: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
ba_cam: 03 00 00 00 00 00 00 00
VIF [0] 94:08:53:8e:ef:21
bssid_cam_idx=0
addr_cam_idx=0
-> bssid_cam_idx=0
sec_cam_bitmap=00 00 00 00 00 00 00 00
STA [0] 38:78:62:8b:cb:c6
addr_cam_idx=0
-> bssid_cam_idx=0
sec_cam_bitmap=00 00 00 00 00 00 00 00
ba_cam tid[6]=0, tid[1]=1
