llist: make llist_add_batch() a static inline
The function is small enough that it should be, and it's a (very) hot path
for io_uring. Doing this actually reduces my vmlinux text size for my
standard build/test box.
Before:
axboe@r7625 ~/g/linux (test)> size vmlinux
text data bss dec hex filename
19892174 5938310 2470432 28300916 1afd674 vmlinux
After:
axboe@r7625 ~/g/linux (test)> size vmlinux
text data bss dec hex filename
19891878 5938310 2470436 28300624 1afd550 vmlinux
