staging: lustre: libcfs: Prevent harmless read underflow

Because this is a post-op instead of a pre-op, then it means we check
if knl_buffer[-1] is a space.  It doesn't really hurt anything, but
it causes a static checker warning so let's fix it.

Fixes: d7e09d0397e8 ("staging: add Lustre file system client support")
