UKSM: cast variable as const

gcc 4.9 produces this error:

mm/uksm.c: In function 'is_full_zero':
mm/uksm.c:169:23: warning: initialization discards 'const' qualifier from pointer target type
error, forbidden warning: uksm.c:169

Casting *src as a constant fixes this. Could also remove the const from the parameter.
