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
