staging: lustre: lustre: libcfs: Replaced printk() with pr_err() 

Author: Tina Johnson <tinajohnson.1234@gmail.com>

The following checkpatch warning was fixed:

Prefer [subsystem eg: netdev]_err([subsystem]dev

with the help of Coccinelle. The following semantic patch was used:

@a@
expression e;
@@

printk(e,...);

@script:python b@
e << a.e;
y;
@@

import re
match = re.match('KERN_ERR ', e);
if (match == None):
    cocci.include_match(False)

else:
    m = re.sub('KERN_ERR ', '', e)
    coccinelle.y = m;

@c@
expression a.e;
identifier b.y;
@@

- printk(e,
+ pr_err(y,
  ...);
