regulator: ab8500: Propagate mode enable read errors
For regulators whose enable and mode share a state field, set_mode()
first reads that field so changing the requested mode does not enable a
disabled rail. A register read error is currently treated as true and
the driver proceeds to write the new mode, potentially enabling a rail
whose state is unknown.
Return the read error without changing the register or cached mode.
