From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The mask of sns_key_info1 suggests the upper nybble is being extracted
however the following shift of 8 bits is too large and always results in
0. Fix this by shifting only by 4 bits to correctly get the upper nybble.
Detected by CoverityScan, CID#142891 ("Operands don't affect result")
Fixes: fa590c222fba ("staging: rts5208: add support for rts5208 and rts5288")
