pm8001: fix a memory leak in flash_update

Browse source 
ccb->fw_control_context is copied to local fw_control_context and
the local variable is never used later

Free ccb->fw_control_context.  The task is forgotten thus also the
reference to fw_control_context and the completion thread takes the info
from virt_ptr again.
