[PATCH] erofs: Use common kernel logging style

From: Joe Perches
Date: Mon Aug 19 2019 - 01:28:50 EST


Rename errln, infoln, and debugln to the typical pr_<level> uses
to the typical kernel styles of pr_<level>

Miscellanea:

o Add newline terminations to the uses
o Use "%s: ...", __func__ and not the atypical "%s, ...", __func__
o Trivial grammar changes in output logging
o Delete the now unused macros
