The variable okay is being initialized with a value that is never
read, it is being re-assigned later on. The initialization is
redundant and can be removed. Also clean up assignment to
variable freespace using an assignment and mask operation.

Cleans up clang scan build warning:
drivers/net/ethernet/xircom/xirc2ps_cs.c:1244:5: warning: Value stored
to 'okay' is never read [deadcode.DeadStores]
