Fix iw txpower syntax

Browse source 
The syntax used to set the txpower is incorrect and misses the keyword "fixed", this results in wireless adapter drivers that only support iw failing to initialize within bettercap.
This bug was introduced in commit bettercap/bettercap@2f3390cf36 which was a fix for issue bettercap/bettercap#657 due to maybe the code not being tested extensively.
