get_kernel_page() was added in 2012 by [1]. It was used for a while for
NFS, but then in 2014, a refactoring [2] removed all callers, and it has
apparently not been used since.
Remove get_kernel_page() because it has no callers.
[1] commit 18022c5d86 ("mm: add get_kernel_page[s] for pinning of
kernel addresses for I/O")
[2] commit 91f79c43d1 ("new helper: iov_iter_get_pages_alloc()")
