4b58dda9fa get_more_jobs: use qb_list_splice instead of iterating list and readding 
oprofile picked up get_more_jobs as a heavy abuser of cpu cycles when running
with cpgbench.  Typical cpgbench runs this function 37 million times.  This
small optimization improves performance of corosync as well as reduces
cpu utilization used by this function.

Might look at tracking length of wait_head and job_head to avoid use of
qb_list_length as well (which also iterates).

9e5385b885 qb_list_splice: don't splice an empty list 
An empty list passed to splice will damage the target splice list.  This patch
prevents that from happening by checking for an empty list and not merging
in that case.
