[PATCH] ext4: Add missing KERN_CONT to a few more debugging uses

From: Joe Perches
Date: Thu Oct 13 2016 - 14:50:48 EST


Recent commits require line continuing printks to always use
pr_cont or KERN_CONT. Add these markings to a few more printks.

Miscellaneaous:

o Integrate the ea_idebug and ea_bdebug macros to use a single
call to printk(KERN_DEBUG instead of 3 separate printks
o Use the more common varargs macro style
