loongarch/mm: stop using pte_ERROR()

Directly use pr_err() in __set_fixmap() and drop pte_ERROR() which helps
in eventually dropping pte_ERROR() macro across the tree.  In this new
printing __FILE__ and __LINE__ has been dropped because they are always
the same and don't really add any value.  The new ptval_to_str() helper is
being used for converting pgtable entry value into a string.  The error
message itself has been cleaned up as well.
