Subject: [PATCH] hostapd: Mark config parameter name const

The functions parsing configuration parameters do not modify the name of
the parameter, so mark that function argument constant. In theory, the
value should also be const, but at least for now, number of the parser
functions end up modifying this to simplify parsing.
