ENGR00291658 PXP: allow PXP device users to submit multiple tasks before start PXP

After the commit "ffcad666548417ef21937e0a755d85ab922313a9" pushed,
adding this support in PXP device driver is also necessary. This
change allows users to submit more than one PXP tasks followd by
only one wait for finished ioctl. It means that users can wait for
more than one tasks done by calling one PXP_IOC_WAIT4CMPLT ioctl.
