afs: Fix setting of mtime when creating a file/dir/symlink
kafs incorrectly passes a zero mtime (ie. 1st Jan 1970) to the server when
creating a file, dir or symlink because the mtime recorded in the
afs_operation struct gets passed to the server by the marshalling routines,
but the afs_mkdir(), afs_create() and afs_symlink() functions don't set it.
This gets masked if a file or directory is subsequently modified.
Fix this by filling in op->mtime before calling the create op.
Fixes: e49c7b2f6de7 ("afs: Build an abstraction around an "operation" concept")
