Subject: ACPI: NUMA: Remove the useless sub table pointer check
Patch-mainline: v5.9-rc1
Git-commit: 1c60f91c319d55058da3a0f6a361b6e6ee6b8c58
References: jsc#SLE-16407

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.
