staging: rtl8723bs: replace ternary min comparison with min()

Change type of local variable wpa_ie_len from int to u8.
wpa_ie_len gets its value either from elems->wpa_ie_len or
elems->rsn_ie_len which are both u8, and thus there's no reason
to cast them to int.

This allows rewriting ternary min comparison using the min() function from
linux/minmax.h as now both sides are unsigned.

Rewrite as well wpa_ie_len + 2 to wpa_ie_len + 2u,
to keep the expression unsigned and avoid overflows.
