[PATCH] mwifiex: start out with BSS type ANY, not STA

From: Brian Norris
Date: Mon Dec 09 2019 - 18:52:49 EST

mwifiex starts out by setting up 3 possible interfaces, but usually only
1 of them gets initialized later. Currently, we leave the
"uninitialized" interfaces with bss_type==0, which means
MWIFIEX_BSS_TYPE_STA. This gives misleading results for things like
mwifiex_get_intf_num(..., MWIFIEX_BSS_TYPE_STA), giving the answer "3"
even when we only have 1 initialized STA.

This bug doesn't affect functions like mwifiex_get_unused_bss_num(),
which are looking at the bss_mode field instead (to see
NL80211_IFTYPE_UNSPECIFIED, which happens to be 0...) for finding
uninitialized interfaces.

Let's make mwifiex_get_intf_num() give a proper answer, by making its
initial value the proper uninitialized value -- ANY.
