power: qpnp-fg: update SRAM data when batt_profile_init is rescheduled

When the charger driver haven't been probed yet and batt_psy is
unavailable, batt_profile_init is rescheduled as it depends on
the charger to disable charging while loading profile. However,
this adds a constraint that SRAM parameters needs to be updated
every time just before batt_profile_init is called again. Else,
stale SRAM parameters will be used to decide whether the battery
profile can be loaded or not.

Hence, cancel and schedule the update_sram_data work whenever
battery profile loading is rescheduled again.
