[PATCH] livepatch: match return value to function signature

[Nicholas Mc Guire]

klp_initialized() should return bool but is actually returning 
struct kobject * - convert it to a boolean explicitly.

static code checking was not happy with
 ./kernel/livepatch/core.c:131 WARNING: return of wrong type
                               bool != struct kobject *

This adds !! to explicitly convert to boolean type.

Patch was compile tested with x86_64_defconfig

patch is against 4.1-rc2 (localversion-next is -next-20150508)
