lib: lz4: fixed zram with lz4 on big endian machines
commit 3e26a691fe3fe1e02a76e5bab0c143ace4b137b4 upstream.
Based on Sergey's test patch [1], this fixes zram with lz4 compression
on big endian cpus.
Note that the 64-bit preprocessor test is not a cleanup, it's part of
the fix, since those identifiers are bogus (for example, __ppc64__
isn't defined anywhere else in the kernel, which means we'd fall into
the 32-bit definitions on ppc64).
Tested on ppc64 with no regression on x86_64.
