[PATCH v2 3/7] powerpc/sstep: Remove empty if statement checking for invalid form

[Cédric Le Goater]

The check should be performed by the caller. This fixes a compile
error with W=1.

../arch/powerpc/lib/sstep.c: In function ‘mlsd_8lsd_ea’:
../arch/powerpc/lib/sstep.c:225:3: error: suggest braces around empty body in an ‘if’ statement [-Werror=empty-body]
   ; /* Invalid form. Should already be checked for by caller! */
   ^
