Subject: [PATCH v2] memblock: Anonotate memblock_is_reserved() with
 __init_memblock.

Found warning:

WARNING: EXPORT symbol "gsi_write_channel_scratch" [vmlinux] version generation failed, symbol will not be versioned.
WARNING: vmlinux.o(.text+0x1e0a0): Section mismatch in reference from the function valid_phys_addr_range() to the function .init.text:memblock_is_reserved()
The function valid_phys_addr_range() references
the function __init memblock_is_reserved().
This is often because valid_phys_addr_range lacks a __init
annotation or the annotation of memblock_is_reserved is wrong.

Use __init_memblock instead of __init.

 Changes v2: correct typo in 'warning'.
