During recovery, XLogNeedsFlush() checks the minimum recovery LSN point instead of the flush LSN point. The same condition checks are used when updating the minimum recovery point in UpdateMinRecoveryPoint(), but are written in reverse order. This commit makes the order of the checks consistent between XLogNeedsFlush() and UpdateMinRecoveryPoint(), improving the code clarity. Note that the second check (as ordered by this commit) relies on InRecovery, which is true only in the startup process. So this makes XLogNeedsFlush() cheaper in the startup process with the first check acting as a shortcut while doing crash recovery, where LocalMinRecoveryPoint is an invalid LSN.
