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 Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
