ath10k: work around uninitialized vht_pfr variable
As clang points out, the vht_pfr is assigned to a struct member without being initialized in one case: drivers/net/wireless/ath/ath10k/mac.c:7528:7: error: variable 'vht_pfr' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized] if (!ath10k_mac_can_set_bitrate_mask(ar, band, mask, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/net/wireless/ath/ath10k/mac.c:7551:20: note: uninitialized use occurs here arvif->vht_pfr = vht_pfr; ^~~~~~~ drivers/net/wireless/ath/ath10k/mac.c:7528:3: note: remove the 'if' if its condition is always true if (!ath10k_mac_can_set_bitrate_mask(ar, band, mask, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/net/wireless/ath/ath10k/mac.c:7483:12: note: initialize the variable 'vht_pfr' to silence this warning u8 vht_pfr; Add an explicit but probably incorrect initialization here. I suspect we want a better fix here, but chose this approach to illustrate the issue.
