cuse(3): Remove PAGE_SIZE from libcuse.

[• hselasky]

Summary

To allow for a dynamic page size on arm64 remove the static value from libcuse.

MFC after: 1 week
Sponsored by: NVIDIA Networking

Test Plan

Should be backwards compatible except for the removal of "CUSE_ALLOC_PAGES_MAX" which I believe is not used at all in user-space.

Don't remember who asked me about this, but here is the patch.

lib/libcuse/cuse_lib.c

should we call getpagesize only once before the loop?

lib/libcuse/cuse_lib.c

This is the exit of the loop. See return below.
