power: qpnp-smbcharger: Fix notifying FG while handling TCC interrupt

Commit 227ab376 ("power: qpnp-smbcharger: only set
CHARGE_DONE if terminated") introduced a change to notify FG to
lower the resume_soc only when the TCC bit is set when the
termination interrupt is handled. This may not work well as the
charge termination interrupt is not a level triggered one but a
pulse. So, just notify FG on the charge termination whenever
TCC interrupt is handled. While at it, remove an unwanted call
of chg_term_handler() from determine_initial_status().
