mfd: lp8788: Fix an error handling path in lp8788_probe()
[ Upstream commit becfdcd75126b20b8ec10066c5e85b34f8994ad5 ]
Should an error occurs in mfd_add_devices(), some resources need to be
released, as already done in the .remove() function.
Add an error handling path and a lp8788_irq_exit() call to undo a previous
lp8788_irq_init().
Fixes: eea6b7cc53aa ("mfd: Add lp8788 mfd driver")
