Colin Ian King 32ae592036 media: cx231xx: fix potential sign-extension overflow on large shift 
Shifting the u8 value[3] by an int can lead to sign-extension
overflow. For example, if value[3] is 0xff and the shift is 24 then it
is promoted to int and then the top bit is sign-extended so that all
upper 32 bits are set.  Fix this by casting value[3] to a u32 before
the shift.

Detected by CoverityScan, CID#1016522 ("Unintended sign extension")

Fixes: e0d3bafd02 ("V4L/DVB (10954): Add cx231xx USB driver")
