PCI: epf-test: Simplify transfers result print

Browse source

In pci_epf_test_print_rate(), instead of open coding a reduction loop to
allow for a division by a 32-bits ns value, simply use div64_u64() to
calculate the transfer rate. To match the printed unit of KB/s, this
calculation divides the rate by 1000 instead of 1024 (that would be KiB/s
unit).

Change the format of the results printed by pci_epf_test_print_rate() to be
more compact without the double new line. Also use dev_info() instead of
pr_info().
