Subject: [PATCH][next] carl9170: Remove redundant assignment to pointer super

The pointer super is being assigned a value that is not being read, it
is being re-assigned later. The assignment is redundant and can be
removed.

Cleans up clang scan warning:
drivers/net/wireless/ath/carl9170/tx.c:192:34: warning: Value stored to
'super' during its initialization is never read [deadcode.DeadStores]
