    UBI: fix sparse errors in ubi.h
    
    In C, signed 1-bit bitfields can only take the values 0 and -1, only 0 and 1
    are ever assigned in current code.  Make them unsigned bitfields.
    
    Fixes the (repeated) sparse errors:
    drivers/mtd/ubi/ubi.h:220:15: error: dubious one-bit signed bitfield
    drivers/mtd/ubi/ubi.h:221:17: error: dubious one-bit signed bitfield
