Subject: [36/90] UBIFS: fix debugging messages

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Artem Bityutskiy <artem.bityutskiy@...ux.intel.com>

commit d34315da9146253351146140ea4b277193ee5e5f upstream.

Patch 56e46742e846e4de167dde0e1e1071ace1c882a5 broke UBIFS debugging messages:
before that commit when UBIFS debugging was enabled, users saw few useful
debugging messages after mount. However, that patch turned 'dbg_msg()' into
'pr_debug()', so to enable the debugging messages users have to enable them
first via /sys/kernel/debug/dynamic_debug/control, which is very impractical.

This commit makes 'dbg_msg()' to use 'printk()' instead of 'pr_debug()', just
as it was before the breakage.
