[PATCH 3/3] media: i2c: imx219: Drop manual fwnode_handle_put() via scope-based cleanup

[Biren Pandya]

Utilize the __free(fwnode_handle) scoped guard macro from <linux/cleanup.h> to automate the lifecycle management of the endpoint fwnode in imx219_check_hwcfg().

This inherently guarantees that the endpoint node is released when it goes out of scope. Consequently, the manual fwnode_handle_put() call in the error_out label is no longer needed and has been removed.
