[PATCH -next v3 10/15] hwmon: (corsair-cpro) Use devm_hid_hw_start_and_open in ccp_probe()

[Li Zetao <lizetao1@huawei.com>]

Currently, the corsair-cpro module needs to maintain hid resources
by itself. Use devm_hid_hw_start_and_open helper to ensure that hid
resources are consistent with the device life cycle, and release
hid resources before device is released. At the same time, it can avoid
the goto-release encoding, drop the out_hw_close and hid_hw_stop
lables, and directly return the error code when an error occurs.
