[PATCH 1/5] libxl: tidy libxl_get_scheduler() according to CODING_STYLE

[Joshua Otto <jtotto@uwaterloo.ca>]

To more closely follow the guidelines in CODING_STYLE, store the result
of the libxc call in the local variable r, and the check the result of
the call in a separate statement.

Additionally, change the error log statement to more accurately reflect
the failure.  This is the only functional change introduced by this
patch.
