[PATCH] Function v9fs_get_idpool returns int, not u32 as called twice…

… in fs/9p/vfs_inode.c

Function v9fs_get_idpool returns int, not u32.  Actually it returns -1 on
errors, and these two callers check if the value is smaller than 0, which
was caught by gcc with extra warning flags.  Compile tested only but should
be OK, as the value computed in v9fs_get_idpool() is also int.
