PCI: rockchip: Handle regulator_get_current_limit() failure correctly
regulator_get_current_limit() can return negative error codes. We saved
the return value in an unsigned "curr", and a subsequent check interpreted
a negative error code as a positive (invalid) current limit.
Save the return code as a signed value, which avoids messages like this,
seen on Samsung Chromebook Plus:
