[lvc-project] [PATCH 2/3] wifi: ath10k: simplify ath10k_peer_assoc_h_vht()

Commit 3db24065c2c8 ("ath10k: enable VHT160 and VHT80+80 modes")
introduces 'get_160mhz_nss_from_maxrate()' which never returns 0,
which means that 'ath10k_peer_assoc_h_vht()' may be simplified.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
