mtd: ubi: annotate fallthrough
The UBI code uses an implicit switch/case fallthrough when handling two
related cases of bad header errors. Also there is a switch/case for unit
prefix handling (G/M/K), which accumulates multiplications.
Add our "fallthrough;" statement-like macro before the respective labels
in both cases, to avoid a warning when GCC's -Wimplicit-fallthrough
warning option is enabled.
