ice: convert ice_reset_vf to take flags

The ice_reset_vf function takes a boolean parameter which indicates
whether or not the reset is due to a VFLR event.

This is somewhat confusing to read because readers must interpret what
"true" and "false" mean when seeing a line of code like
"ice_reset_vf(vf, false)".

We will want to add another toggle to the ice_reset_vf in a following
change. To avoid proliferating many arguments, convert this function to
take flags instead. ICE_VF_RESET_VFLR will indicate if this is a VFLR
reset. A value of 0 indicates no flags.

One could argue that "ice_reset_vf(vf, 0)" is no more readable than
"ice_reset_vf(vf, false)".. However, this type of flags interface is
somewhat common and using 0 to mean "no flags" makes sense in this
context. We could bother to add a define for "ICE_VF_RESET_PLAIN" or
something similar, but this can be confusing since its not an actual bit
flag.

This paves the way to add another flag to the function in a following
change.
