exportfs: use pr_debug for unreachable debug statements
[ Upstream commit 427505ffeaa464f683faba945a88d3e3248f6979 ]
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.
