Fix assert in FreeBSD-specific dmu_read_pages

Browse Source 
The function has three similar pieces of code: for read-behind pages,
requested pages and read-ahead pages.  All three pieces had an
assert to ensure that the page is not mapped.  Later the assert was
relaxed to require that the page is not mapped for writing.  But that
was done in two places out of three.  This change fixes the third piece,
read-ahead.
