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.
