[PATCH] 9p: fix debug compilation error

[Eric Van Hensbergen <ericvh@gmail.com>]

From: Meelis Roos <mroos@linux.ee>

With 9P but no 9P debug options, this error occurs:
  CC [M]  fs/9p/v9fs.o
fs/9p/v9fs.c: In function 'v9fs_parse_options':
fs/9p/v9fs.c:134: error: 'p9_debug_level' undeclared (first use in this function)

The following patch moves the definition of p9_debug_level out of #ifdef
and seems to fix the problem.

(Original patch took care of the extern definition in the includes, but
not the actual definition in mod.c - ericvh)
