btrfs-progs: check: Output verbose error when fsck found a bug in any tree

Browse Source 
Although we output error like "errors found in extent allocation tree or
chunk allocation", but we lacks such output for other trees, but leaving
the final "found error is %d" to catch the last return value(and
sometime it's cleared)

This patch adds extra error message for top level error path, and modify
the last "found error is %d" to "error(s) found" or "no error found".
