UBIFS: return sensible error codes
When mounting/re-mounting, UBIFS returns EINVAL even if the ENOSPC
or EROFS codes are are much better, just because we have not found
references to ENOSPC/EROFS in mount (2) man pages. This patch
changes this behaviour and makes UBIFS return real error code,
because:
1. It is just less confusing and more logical
2. mount is not described in SuSv3, so it seems to be not really
well-standartized
3. we do not cover all cases, and any random undocumented in man
pages error code may be returned anyway
