[PATCH 08/41] drivers: tty: serial: sb1250-duart: fix checkpatch warning on printk()

checkpatch complaints:

WARNING: printk() should include KERN_<LEVEL> facility level
#698: FILE: drivers/tty/serial/sb1250-duart.c:698:
+ printk(err);

WARNING: printk() should include KERN_<LEVEL> facility level
#706: FILE: drivers/tty/serial/sb1250-duart.c:706:
+ printk(err);

Even though it's a false alarm here (the string is already prefixed
w/ KERN_ERR), it's nicer to use pr_err() here, which also makes
checkpatch happy.
