media: rc: st_rc: Fix reset control resource leak
The driver calls reset_control_get_optional_exclusive() but never calls
reset_control_put() in error paths or in the remove function. This causes
a resource leak when probe fails after successfully acquiring the reset
control, or when the driver is unloaded.
Switch to devm_reset_control_get_optional_exclusive() to automatically
manage the reset control resource.
Fixes: a4b80242d046 ("media: st-rc: explicitly request exclusive reset control")
