[hackers] [dwm][PATCH v3] manage: For isfloating/oldstate check/set, ensure trans client actually exists

[m]

From: Miles Alan <m...@milesalan.com>

In certain instances trans may be set to a window that doesn't actually
map to a client via wintoclient; in this case it doesn't make sense
to set isfloating/oldstate since trans is essentially invalid in that
case / correlates to the above condition check where trans is set /
XGetTransientForHint is called.
