The left shift is followed by a re-assignment back to cc_css, the
assignment is redundant. Fix this by replacing the "<<=" operator with
"<<" instead.
This cleans up the clang scan build warning:
drivers/nvme/target/core.c:1124:10: warning: Although the value stored to 'cc_css' is used in the enclosing expression, the value is never actually read from 'cc_css' [deadcode.DeadStores]
