ice: Fix DSCP PFC TLV creation

Browse Source 
When creating the TLV to send to the FW for configuring DSCP mode PFC,the
PFCENABLE field was being masked with a 4 bit mask (0xF), but this is an 8
bit bitmask for enabled classes for PFC.  This means that traffic classes
4-7 could not be enabled for PFC.

Remove the mask completely, as it is not necessary, as we are assigning 8
bits to an 8 bit field.
