[PATCH v2 5/5] Revert "tpm: do not ignore memblock_reserve return value"

This reverts commit c33c28f9f6e017702374e1ab907dfa5a63db5301.

efi_tpm_eventlog_init() runs from efi_config_parse_tables() during early
EFI initialization, before memblock_allow_resize(). At that point
memblock_reserve() either succeeds or panics, never returning an error.

Therefore the return value check is unreachable, so restore the original
unconditional memblock_reserve().

No functional change.
