glsl: Fix hypothetical NULL dereference related to process_array_type
Ensure that process_array_type never returns NULL, and let
process_array_type handle the case where the supplied base type is NULL.
Fixes issues identified by Klocwork analysis:
Pointer 'type' returned from call to function 'get_type' at line
1907 may be NULL and may be dereferenced at line 1912.
and
Pointer 'field_type' checked for NULL at line 4160 will be
dereferenced at line 4165. Also there is one similar error on line
4174.
