iwlwifi: mvm: Change number of DTIMs to skip semantics

Browse Source 
If skip over DTIMs is enabled the driver can specify number of DTIMs
to skip. This parameter in host-device API implies number of DTIM
periods to skip. For example, to skip one DTIM means sleep over two
DTIM periods. Change semantics accordingly. Change this parameter's
default value.
