[PATCH 2/3] ACPI: NUMA: Remove the useless sub table pointer check

[Hanjun Guo <guohanjun@huawei.com>]

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 those callback
handlers.
