MdeModulePkg/BdsDxe: Fix calling PlatformBootManagerWaitCallback on 0
Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=2266 Commit 2de1f611be06ded3a59726a4052a9039be7d459b introduced a regression whereas platforms that did set PcdPlatformBootTimeOut to 0 are now getting an unexpected call to PlatformBootManagerWaitCallback(). This patch also ensures that, if PcdPlatformBootTimeOut is 0xFFFF we don't call PlatformBootManagerWaitCallback() with a zero argument as doing so would produce an unwarranted jump to full progress completion which is likely to throw off users.
