Felix Fietkau 1ba5cc4b40 wifi: mt76: mt7925: drop redundant chandef.chan NULL check in MT7927 path
In mt7925_mac_link_bss_add(), the MT7927 branch added an else-if that
checked mvif->phy->mt76->chandef.chan before assigning it to the local
chan pointer. If that check failed, chan stayed NULL and chan->band was
dereferenced unconditionally a line later.

phy->chandef.chan is set during phy registration in mt76_check_sband()
and is never cleared, so the check is a no-op. Drop it and use the
chandef channel as an unconditional fallback, matching the assumption
made elsewhere in the driver (e.g. the existing basic_rates_idx
selection right below this block and mt7925/mac.c).
