fs: Rename page_offset() to page_pos()

page_offset() is at best an ambiguous name for this function (returning
the byte offset in the file of this page).  At least one regular
contributor thought it returned the pgoff_t of the page.  We tend to use
a variable named page_offset to mean the byte offset from the start of
the page, which is also not what page_offset() does.

Fortunately, we have an unambiguous name for the offset in bytes from
the beginning -- pos.  The most common name for an loff_t is 'pos'
(by 773 to 575 for 'offset'), so page_pos() seems like the best name
for this function.

Conversion performed automatically by Coccinelle with this script:

@@ expression a; @@
-       page_offset(a)
+       page_pos(a)
