This should probably change to use new spl_decompression_enabled(),
such change should be made in the GZIP patch.

Could probably be simplified to something like:
if (spl_decompression_enabled() &&
(image_comp == IH_COMP_GZIP || image_comp == IH_COMP_LZMA))
Also what happens if I run a SPL without compression enabled, but have a
FIT with image parts that is compressed?
