Designed behaviour. sys_delete_module only removes autoclean modules
that have been used at least once, either they have been used or some
other module has a reference to them. Otherwise you get nasty races
like this
cpu 0 cpu 1
request_module(foo)
modprobe -k foo
insmod -k foo
foo is loaded, unused
kernel sees foo has loaded
rmmod -a
kernel uses foo
