asoc: codec: swr-haptics: update slave-vdd regulator control logic

Update the slave-vdd regulator control logic to avoid unbalanced
regulator_enable() regulator_disable() calls. Meanwhile, correct
the jump label when bailing out from soundwire enumeration failure.
This helps to avoid the regulator_put() call in the device remove
process throwing a warning for a dangling regulator enable status.
