MdeModulePkg/BdsDxe: Fix calling PlatformBootManagerWaitCallback on 0

Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=2266

Commit 2de1f611be 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.
