wifi: mm81x: clamp tx width to stas max supported width

Browse source

max_bw_mhz is not populated with the stas maximum supported width
during association. This means data frames are sent at the operating
width, regardless of whether the sta can support the operating width.
For example a STA that supports up to 4MHz receiving frames from an AP
running on an 8MHz operating channel will be sent frames at 8MHz which
it cannot receive.

Make sure we initialise the stas maximum support bandwidth and while
we are here rename it to max_rx_bw_mhz to indicate its the maximum
bandwidth the sta can receive frames from.

Note: This should be conveyed via ieee80211_link_sta::bandwidth, but
the ieee80211_sta_rx_bandwidth enum does not support S1G widths as of
now and will require some non-trivial work to support in the future.
