afs: Remove 'retry' arg from afs_FindVCache
Since OpenAFS 1.0, afs_FindVCache has had an optional 'retry' output
arg. The relevant functionality appears to have been specific to Irix
versions before 5.3, but even OpenAFS 1.0 only had param.h files and
general build logic for Irix 6.2 and later.
With commit
13e44b2b (afs: Refactor osi_vnhold/AFS_FAST_HOLD), the
unused 'retry' argument has now been removed from the lower-level
osi_vnhold function, so now remove it from afs_FindVCache and related
comments, and remove the associated logic to handle a non-zero
'retry'.
