    afs: Return memcache allocation errors
    
    During cache initialization, we can fail to allocate our dcache
    entries for memcache. Currently when this happens, we just log a
    message and try to disable dcache access. However, this results in at
    least one code path that causes a panic anyway during startup, since
    afs_CacheTruncateDaemon will try to trim the cache, and afs_GetDownD
    will call afs_MemGetDSlot, and we cannot find the given dslot.
    
    To avoid this, change our cache initialization to return an error,
    instead of trying to continue without a functional dcache. This causes
    afs_dcacheInit to return an error in this case, and by extension
    afs_CacheInit and the AFSOP_CACHEINIT syscall. Also change afsd to
    actually detect errors from AFSOP_CACHEINIT, and to bail out when it
    does.
    
    Thanks to gsgatlin@ncsu.edu for reporting the relevant panic.
