V4L/DVB (10761): cx18: Change log lines for internal subdevs and fix tveeprom reads 

Give messages originating from internal subdevs a header using the subdev's
name.  Fixed an uninitialized variable problem with reading the EEPROM, noticed
from log output.  Got rid of the unused cx18_av_exit() function.
