extcon: Fix error handling in extcon_dev_register

[ Upstream commit d3bdd1c3140724967ca4136755538fa7c05c2b4e ]

When devm_kcalloc() fails, we should execute device_unregister()
to unregister edev->dev from system.

Fixes: 046050f6e623e ("extcon: Update the prototype of extcon_register_notifier() with enum extcon")
