Rework the fbdev deferred-I/O to not interfere with fields of struct
page. All references from deferred-I/O code to fields in struct page
are gone. The rsp state is held in a separate pageref structure.

v4:
	* fix locking in fb_mmap() (Dan)
	* fix commit-message style (Javier)
v3:
	* rename pagelist to pagereflist (Sam)
	* use pageref->offset over page->index (Javier)
v2:
	* split off from a larger patchset [1]
