media: ddbridge: fix impossible condition warning
Smatch and gcc complained:
drivers/media/pci/ddbridge/ddbridge-core.c:3491 bpsnr_show() warn: impossible condition '(snr[0] == 255) => ((-128)-127 == 255)'
drivers/media/pci/ddbridge/ddbridge-core.c: In function ‘bpsnr_show’:
drivers/media/pci/ddbridge/ddbridge-core.c:3491:13: warning: comparison is always false due to limited range of data type [-Wtype-limits]
Fix this by changing the type of snr to unsigned char.
