power: supply: da9150: Remove redundant error logging
Commit Message
A call to platform_get_irq_byname() already prints an error on failure
within its own implementation. So printing another error based on its
return value in the caller is redundant and should be removed. The
clean up also makes if condition block braces and the device pointer
variable dev unnecessary. Remove those as well.
Issue identified using platform_get_irq.cocci coccinelle semantic patch.
