9P compile fix

[Meelis Roos]

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 compilation.
