Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

This patch fixes the tvp5150_read() function to return an error in case
the I2C transaction fails.
tvp5150_probe() and other relevant driver callbacks changed to check the
status of the I2C read operations.
In case of a read error throw an error message with v4l2_err()
instead of v4l2_dbg().
