kobject_uevent: Fix OOB access within zap_modalias_env()
commit dd6e9894b451e7c85cceb8e9dc5432679a70e7dc upstream.
zap_modalias_env() wrongly calculates size of memory block to move, so
will cause OOB memory access issue if variable MODALIAS is not the last
one within its @env parameter, fixed by correcting size to memmove.
