Variable 'ps' is set to wdev->ps but this value is never read as it is overwritten with a new value later on, hence it is a redundant assignment and can be removed.
Cleans up the following clang-analyzer warning:
net/wireless/wext-compat.c:1170:7: warning: Value stored to 'ps' during its initialization is never read [clang-analyzer-deadcode.DeadStores]
