[PATCH 17/38] tick-common: call tick_install_replacement() from tick_check_new_device()

[Viresh Kumar]

Part of tick_check_new_device() is exactly same as what's being done by
tick_install_replacement(). And so we can actually call
tick_install_replacement() directly from tick_check_new_device() instead of
replicating code.
