btrfs: replace kmap() with kmap_local_page() in lzo.c
The use of kmap() is being deprecated in favor of kmap_local_page() where
it is feasible. With kmap_local_page(), the mapping is per thread, CPU
local and not globally visible.
Therefore, use kmap_local_page() / kunmap_local() in lzo.c wherever the
mappings are per thread and not globally visible.
Tested on QEMU + KVM 32 bits VM with 4GB of RAM and HIGHMEM64G enabled.
