Currently, shutdown for l3fwd-power application is all over the place
and may or may not happen either in the signal handler or in the main()
function. Fix this so that the signal handler will only set the exit
variable, thereby allowing all of the loops to end properly and proceed
to deinitialize everything.

Currently, if power library initialization fails, only a log message is
displayed. This is suboptimal for a number of reasons, but the main one
is that telemetry mode does not depend on the power library and can
therefore run in environments where l3fwd-power would normally not run
correctly (such as inside a VM). This will lead to attempts to
deinitialize the power library on exit, with a subsequent forced unclean
shutdown of DPDK.
Fix this by only initializing the power library in modes that actually
need it, and change a log message to a failure to initialize.

Subject: [dpdk-dev] [PATCH v2 1/2] l3fwd-power: exit if initializing power library failed
Currently, if power library initialization fails, only a log message is displayed. This is suboptimal for a number of reasons, but the main one is that telemetry mode does not depend on the power library and can therefore run in environments where l3fwd-power would normally not run correctly (such as inside a VM). This will lead to attempts to deinitialize the power library on exit, with a subsequent forced unclean shutdown of DPDK.
Fix this by only initializing the power library in modes that actually need it, and change a log message to a failure to initialize.
