media: bt8xx: Remove unnecessary self-assignment
Clang warns when a variable is assigned to itself.
drivers/media/pci/bt8xx/bttv-driver.c:2043:13: warning: explicitly
assigning value of variable of type '__s32' (aka 'int') to itself
[-Wself-assign]
min_height = min_height;
~~~~~~~~~~ ^ ~~~~~~~~~~
1 warning generated.
There doesn't appear to be any good reason for this and this statement
was added in commit e5bd0260e7d3 ("V4L/DVB (5077): Bttv cropping
support") back in 2007. Just remove it.
