UBI: print less
UBI currently prints a lot of information when it mounts a volume, which bothers some people. Make it less chatty - print only important information by default. Get rid of 'dbg_msg()' macro completely. Reported-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
