netfilter: xtables: change hotdrop pointer to direct modification
Since xt_action_param is writable, let's use it. The pointer to
'bool hotdrop' always worried (8 bytes (64-bit) to write 1 byte!).
Surprisingly results in a reduction in size:
text data bss filename
5457066 692730 357892 vmlinux.o-prev
5456554 692730 357892 vmlinux.o
