Allow valid pages to be mapped for read access when they have a non-zero
busy count.  Only mappings that allow write access should be prevented by
a non-zero busy count.

(The prohibition on mapping pages for read access when they have a non-
zero busy count originated in revision 1.202 of i386/i386/pmap.c when
this code was a part of the pmap.)
