Subject: [PATCH] lib : lz4 using put_unaligned_le16 instead of put_unaligned


In case of mips bigendian machine, put_unaligned writes bigendian bytes order. 
This is defined in arch/mips/include/asm/unaligned.h. So it's right use put_unaligned_le16 function instead of put_unaligned.
This patch also fixes problem fail to mount zram ext4 partition with "zram: Decompression failed! err=-1, page=0" in mips bigendian machine.
