[SRU][Zesty][PATCH 4/4] staging: rtl8192e: GetTs Fix invalid TID 7 warning.

[Joseph Salisbury]

From: Malcolm Priestley <tvboxspy at gmail.com>

BugLink: http://bugs.launchpad.net/bugs/1698470

TID 7 is a valid value for QoS IEEE 802.11e.

The switch statement that follows states 7 is valid.

Remove function IsACValid and use the default case to filter
invalid TIDs.
