libsmbconf:registry: rework smbconf_reg_parameter_forbidden(), renaming it.

The logic is inverted, the lp_parameter_is_invalid call of
smbconf_reg_valname_valid() is included, and the function
is renamed to smbconf_reg_parameter_is_valid().

Use the new function everywhere in smbconf registry backend.
And remove corresponding reverse function smbconf_reg_valname_valid().
