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

The following checkpatch warning was fixed:

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

with the help of Coccinelle. pr_cont() was used to replace those printk
statements which followed a printk that did not end with a '\n'. The following
semantic patch was used to replace printk() with pr_err():

@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,
  ...);
