libafs: afs_CacheFetchProc can't be called without a dcache pointer

Browse Source 
An inspection of the only call site suggests that afs_CacheFetchProc()
can't be called with a null dcache pointer, and code further down
in this function dereferences adc unconditionally (assuming
rxfs_fetchInit() doesn't crash first) so remove the conditional
here.

Probably more of these parameters can and should be included in the
AFS_NONNULL.
