linux, compat: add missing definitions for ubi
add missing definitions for the ubi/ubifs sync with linux 4.2, also change "#define kfree ..." into a static inline, so prevent ubi compile error: CC drivers/mtd/ubi/fastmap.o drivers/mtd/ubi/fastmap.c: In function 'scan_pool': drivers/mtd/ubi/fastmap.c:475:3: error: called object 'free' is not a function Signed-off-by: Heiko Schocher <hs@denx.de>
