marius 4594375cbb Revert the use of BUS_DMA_ALLOCNOW when creating the DMA tag for user
data introduced in r236061. Using that flag doesn't make that much
sense on this case as the DMA maps using it are also created during
sym_pci_attach(). Moreover, due to the maxsegsz parameter used, doing
so may exhaust the bounce pages pool on architectures requiring
bounce pages. [1]
While at it, use a slightly more appropriate maxsegsz parameter.

README.sym
----------
This file was bundled with the `sym' driver source files, when 
the driver was in development stage and not included yet into 
the FreeBSD repository. It described how to install the driver, 
gave informations on driver features and summerized important 
changes between versions. These informations are now available 
using `man sym' for driver usage and features description, and 
`cvs log' for driver changes.

I haven't removed this README file from the repository since 
I may have to provide additional documentation to people 
interested in understanding the driver sources and/or in helping 
driver development and maintenance.

As a result, this file is now under reconstruction. :-)
