lib/decompress.c add __init to decompress_method and data
Fix the warning: WARNING: vmlinux.o(.text+0x14cfd8): Section mismatch in reference from the variable compressed_formats to the function .init.text:gunzip() The function compressed_formats() references the function __init gunzip(). etc.. Within decompress.c, compressed_formats[] needs 'a __initdata annotation', because some of it's data members refer to functions which will be unloaded after init. Consequently, its user decompress_method() will get the __init prefix.
