exportfs: use pr_debug for unreachable debug statements 

[ Upstream commit 427505ffea ]

expfs.c has a bunch of dprintk statements which are unusable due to:
 #define dprintk(fmt, args...) do{}while(0)
Use pr_debug so that they can be enabled dynamically.
Also make some minor changes to the debug statements to fix some
incorrect types, and remove __func__ which can be handled by dynamic
debug separately.
