Subject: [PATCH] block: drop extra (and bogus) printk

When setting an invalid scheduler through sysfs, two log entries will be
added.  Also, when running 'echo foo > /sys/block/DISK/queue/scheduler'
the second one will includes the extra '\n':

[10465.216944] elevator: type foo not found
[10465.216953] elevator: switch to foo
 failed

This patch simply drops the second printk().
