drivers/misc/altera-stapl/altera.c: remove extraneous KERN_INFO prefix

The KERN_INFO prefix is being prepended to KERN_DEBUG when using the
dprink macro, Remove it as it is extraneous since we are printing the
message out as debug via dprintk().

Fixes smatch warning:

drivers/misc/altera-stapl/altera.c:2454 altera_init()
   warn: KERN_* level not at start of string
