printk: Remove obsoleted check for non-existent "user" object
The original check for non-null "user" object was introduced by commit
e11fea92e13f ("kmsg: export printk records to the /dev/kmsg interface")
when "user" could be NULL if /dev/ksmg was opened for writing.
Subsequent change 750afe7babd1 ("printk: add kernel parameter to control
writes to /dev/kmsg") made "user" context required for files opened for
write, but didn't remove now redundant checks for it to be non-NULL.
This patch removes the dead code while preserving the current logic.
