net: ieee802154: mcr20a: Fix lifs/sifs periods

Browse source 
commit d753c40048 upstream.

These periods are expressed in time units (microseconds) while 40 and 12
are the number of symbol durations these periods will last. We need to
multiply them both with phy->symbol_duration in order to get these
values in microseconds.
