[PATCH] sunvdc: update outdated comment

[Kexin Sun]

The function do_generic_file_read() was renamed
generic_file_buffered_read() by commit 47c27bc46946 ("fs: pass iocb
to do_generic_file_read"), and later renamed again to filemap_read()
by commit 87fa0f3eb267 ("mm/filemap: rename generic_file_buffered_read
to filemap_read"). Update the comment accordingly.
