Fix tuner max range
From: Mauro Carvalho Chehab <mchehab@infradead.org>
By default, tuner-core reports max range as the maximum possible
unsigned int. Since qv4l2 uses QSpinBox to display frequency ranges, and
this waits for a signed integer, it is considering the maximum value as
being -1.
This hack will trunc any value bigger than the maximum signed integer to
the max value.
