wifi: mt76: mt7915: do not check state before configuring implicit beamform

[ Upstream commit d2b5bb6dfab29fe32bedefaade88dcd182c03a00 ]

Do not need to check running state before configuring implicit Tx
beamform. It is okay to configure implicit Tx beamform in run time.
Noted that the existing connected stations will be applied for new
configuration only if they reconnected to the interface.
