media: dvbdev: fix the logic when DVB_DYNAMIC_MINORS is not set
commit
a4aebaf6e6efff548b01a3dc49b4b9074751c15b upstream.
When CONFIG_DVB_DYNAMIC_MINORS, ret is not initialized, and a
semaphore is left at the wrong state, in case of errors.
Make the code simpler and avoid mistakes by having just one error
check logic used weather DVB_DYNAMIC_MINORS is used or not.
