UBIFS: introduce mounting flag
This is a preparational patch which removes the 'c->always_chk_crc' which was set during mounting and remounting to R/W mode and introduces 'c->mounting' flag which is set when mounting. Now the 'c->always_chk_crc' flag is the same as 'c->remounting_rw && c->mounting'. This patch is a preparation for the next one which will need to know when we are mounting and remounting to R/W mode, which is exactly what 'c->always_chk_crc' effectively is, but its name does not suite the next patch. The other possibility would be to just re-name it, but then we'd end up with less logical flags coverage. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
