[COMMITTED] BZ #19086: Fix documented argument order for posix_fallocate64.

[Carlos O'Donell]

The argument order for posix_fallocate64 in the manual
was wrong, it was listed as [fd, len, offset] when it
should have been [fd, offset, len].

Verified io/fcntl.h has the right argument order, and it
does. Verified generated PDF.

Checked in.
