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.
