ACPI: NUMA: Remove the useless sub table pointer check 



In acpi_parse_entries_array(), the subtable entries (entry.hdr)
will never be NULL, so for ACPI subtable handler in struct
acpi_subtable_proc, will never handle NULL subtable entries.

Remove those useless subtable pointer checks in the callback
handlers.
