Jeff Layton ed1869a252 lockd: set file_lock start and end when decoding nlm4 testargs
commit 7ff84910c6 upstream.

Commit 6930bcbfb6 dropped the setting of the file_lock range when
decoding a nlm_lock off the wire. This causes the client side grant
callback to miss matching blocks and reject the lock, only to rerequest
it 30s later.

Add a helper function to set the file_lock range from the start and end
values that the protocol uses, and have the nlm_lock decoder call that to
set up the file_lock args properly.

Fixes: 6930bcbfb6 ("lockd: detect and reject lock arguments that overflow")
