afs: Remove unused constant DCSIZE
The size of the dcache hash table is automatically determined
from the size of the vcache hash table size, since even before
the initial OpenAFS 1.0 release. AFS 3.3 had constants
DCHASHSIZE and DVHASHSIZE which were used to size the respective
hash tables, but DCSIZE was unused even there.
