printk: remove obsolete dead assignment
Commit 849f3127bb46 ("switch /dev/kmsg to ->write_iter()") refactored
devkmsg_write() and left over a dead assignment on the variable 'len'.
Hence, make clang-analyzer warns:
kernel/printk/printk.c:744:4: warning: Value stored to 'len' is never read
[clang-analyzer-deadcode.DeadStores]
len -= endp - line;
^
Simply remove this obsolete dead assignment here.
