receive: denyCurrentBranch=updateinstead should not blindly update
The handling of receive.denyCurrentBranch=updateInstead was added to a switch statement that handles other values of the variable, but all the other case arms only checked a condition to reject the attempted push, or let later logic in the same function to still intervene, so that a push that does not fast-forward (which is checked after the switch statement in question) is still rejected. But the handling of updateInstead incorrectly took immediate effect, without giving other checks a chance to intervene. Instead of calling update_worktree() that causes the side effect immediately, just note the fact that we will need to call the function later, and first give other checks a chance to reject the request. After the update-hook gets a chance to reject the push (which happens as the last step in a series of checks), call update_worktree() when we earlier detected the need to.
