zlogger: switch from kzalloc to __get_free_pages

Since we want to mmap the memory in userspace, it's important for the
memory to be consisting of full pages. Even though this has been true in
our tests, kzalloc does not guarantee this and there is a danger of this
changing in the future kernel releases. Instead, we can use
__get_free_pages, which explicitly returns a number of contiguous pages.
