Applying ++ to a bool is equivalent to setting it true, regardless of
its initial value (bools are not uint1_t). Hence the function
wl_get_vif_state_all can only ever return true/false. The only in-tree
caller uses its return value as a boolean. So update its return type,
and since the list traversal and bit testing have no side effects,
just return true immediately. Its return value tells if any vif is up,
- Now I may be really nit-picking, but the return value if any vif is *in
- the specified state*.

so also rename it to brcmf_get_vif_state_any.

Notes:
v2: Rename wl_get_vif_state_all => brcmf_get_vif_state_any as
requested by Arend.
