power: qpnp-fg: Clear VACT_INT_ERROR after IMA error recovery 



Currently when the IMA error recovery sequence is executed, we
restore some of the SRAM registers backed up. This includes
VACT_INT_ERROR as well. However, we have to clear VACT_INT_ERROR
for a good starting point after resetting FG. This will help in
accuracy of the SOC reported.
