zd1211rw: lower hw command timeouts

Device command timeouts are set up very high (1 sec) and this causes
AP beacon to lock up for long for example. Checking timeouts on device
it's easy to see that 1 sec timeout is not needed, when device fails
to response longer timeout doesn't help:

[  473.074419] zd1211rw 1-1:1.0: print_times() Read times:
[  473.175163] zd1211rw 1-1:1.0: print_time()     0 - 10 msec: 1506

[  473.182101] zd1211rw 1-1:1.0: print_time()  251 - 500 msec: 0
[  473.183221] zd1211rw 1-1:1.0: print_time() 500 - 1000 msec: 20
[  473.184381] zd1211rw 1-1:1.0: print_time() 1000 - ... msec: 18

Also vendor driver doesn't use this long timeout. Therefore change
timeout to 50msec.
