mt76: fix enum type mismatch

There is no 'NONE' version of 'enum mcu_cipher_type', and returning
'MT_CIPHER_NONE' causes a warning:

drivers/net/wireless/mediatek/mt76/mt7921/mcu.c: In function 'mt7921_mcu_get_cipher':
drivers/net/wireless/mediatek/mt76/mt7921/mcu.c:114:24: error: implicit conversion from 'enum mt76_cipher_type' to 'enum mcu_cipher_type' [-Werror=enum-conversion]
  114 |                 return MT_CIPHER_NONE;
      |                        ^~~~~~~~~~~~~~

Add the missing MCU_CIPHER_NONE defintion that fits in here with
the same value.
