Staging: vme: devices: Use kasprintf

Browse Source 
This patch uses kasprintf which combines kmalloc and sprintf.
kasprintf also takes care of the size calculation.

This is done using Coccinelle. Semantic patch used is as follows:

@@
expression a,flag;
expression list args;
statement S;
@@

 a =
- \(kmalloc\|kzalloc\)(...,flag)
+ kasprintf (flag,args)
  <... when != a
  if (a == NULL || ...) S
  ...>
- sprintf(a,args);
