tap: Rename tap_iov_{base,len}

These two functions are typically used to calculate values to go into the
iov_base and iov_len fields of a struct iovec.  They don't have to be used
for that, though.  Rename them in terms of what they actually do: calculate
the base address and total length of the complete frame, including both L2
and tap specific headers.
