chgstv2: Always check batt disconnect state.
When the battery is responsive, the charge state machine only checks the
disconnect state if the battery requests 0 volts and 0 milliamps. Since
battery disconnect state essentially means "can the battery provide a
charge?" we should always check the battery disconnect state. It's
possible that the battery wants a charge to recover from a short term
failure, but cannot yet provide charge to the system.
This commit simply changes battery_seems_to_be_disconnected to always
query the disconnect state regardless of the request charge voltage and
current.
BUG=b:76121712
BRANCH=None
TEST=Flash nocturne; cutoff battery, verify that battery is able to
recover and system is able to boot.
