[PATCH] PM / devfreq: Fix error code propagation in devm_devfreq_event_add_edev()

[Kaushlendra Kumar <kaushlendra.kumar@intel.com>]

Fix incorrect error code return in devm_devfreq_event_add_edev() when
devfreq_event_add_edev() fails. The function was unconditionally
returning -ENOMEM regardless of the actual error returned by
devfreq_event_add_edev().

The devfreq_event_add_edev() function can fail for various reasons:
- Invalid parameters (-EINVAL)
- Memory allocation failure (-ENOMEM)
- Device registration failure (various error codes)

This change ensures that callers receive the accurate error information,
improving error handling and debugging capabilities in the devfreq
event subsystem.
