power: qpnp-fg: Do not return -EAGAIN when handling IMA error during probe 



Currently, when an IMA error is seen while doing a SRAM access
driver returns -EAGAIN. This is fine as such however this can
cause a failure during probe where the error is checked and
handled well before SRAM access can be made. Fix this.
