Re: [XEN PATCH] libxl: Check return value of libxl__xs_directory in name2bdf

libxl__xs_directory() can potentially return NULL without setting `n`.
As `n` isn't initialised, we need to check libxl__xs_directory()
return value before checking `n`. Otherwise, `n` might be non-zero
with `bdfs` NULL which would lead to a segv.
