If you are fine with losing the data, you can reflash the os (https://www.google.com/url?sa=t&source=w...) over the bootloader interface. That would remove CyanogenMod and wipe your data, but your phone should run properly on stock Android again. since your bootloader is unlocked, you could also flash just a new custom recovery, for example twrp, and use it to flash a zip containing CyanogenMod, if you have one have one on your phone. The procedure is basically the same, but instead of downloading the system image, you download the custom recovery and run the command "fastboot flash recovery <file path for custom recovery>" to just flash the recovery.
