[PATCH] ubi: fix sparse errors in ubi.h

[Harvey Harrison]

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
drivers/mtd/ubi/ubi.h:222:18: error: dubious one-bit signed bitfield
drivers/mtd/ubi/ubi.h:223:16: error: dubious one-bit signed bitfield
drivers/mtd/ubi/ubi.h:224:20: error: dubious one-bit signed bitfield

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.
