[PATCH] AFS: Guard afs_file_readpage_read_complete() definition with CONFIG_AFS_FSCACHE

[David Howells <dhowells@redhat.com>]

From: Matt Kraai <kraai@ftbfs.org>

If CONFIG_AFS_FSCACHE is not defined, the following warning is displayed when
fs/afs/file.c is compiled:

 fs/afs/file.c:111: warning: ‘afs_file_readpage_read_complete’ defined but not used

This occurs because all calls to this function are guarded by
CONFIG_AFS_FSCACHE.  Thus, guard its definition as well.
