[XFS] Fixed a few bugs in xfs_buf_associate_memory()
- calculation of 'page_count' was incorrect as it did not
consider the offset of 'mem' into the first page. The
logic to bump 'page_count' didn't work if 'len' was <=
PAGE_CACHE_SIZE (ie offset = 3k, len = 2k).
- setting b_buffer_length to 'len' is incorrect if 'offset'
is > 0. Set it to the total length of the buffer.
- I suspect that passing a non-aligned address into
mem_to_page() for the first page may have been causing
issues - don't know but just tidy up that code anyway.
