Debugfs pdev entries should be cleaned up during the crash
on recovery. If not, mac register will fail for the reason
that it is already registered during core reconfigure.

After setting fixed vht-rate if new station is trying to
assoc with mu_bfee cap, or if a sta is already connected
with mu_bfee cap then set the fixed vht-rate and
reconnecting the sta, FW assert is happening.
So to avoid this, reset the MU_BEAMFORMEE bit in vht->caps,
if mcs_index is invalid for nss 1.

Rx_filter flags are set with default filter flags during
wifi up/down sequence even though the 'ext_rx_stats' debugfs
is enabled as 1. So, that we are not getting proper per peer
rx_stats.
Hence, fixing this by setting the missing rx_filter when
ext_rx_stats is already set/enabled.
