[RFC 3/3] examples/bond: fix invalid use of trylock

[Mattias Rönnblom]

The conditional rte_spinlock_trylock() was used as if it is an
unconditional lock operation in a number of places.

Fixes: cc7e8ae84faa ("examples/bond: add example application for link bonding 
mode 6")
Cc: michalx.k.jastrzeb...@intel.com
