[PATCH] ntb_perf: Fix printk format

[Max Hawking]

The correct printk format is %pa or %pap, but not %pa[p].

For some reason this patch isn't applying cleanly for me, I'm seeing
the following issue:
$ b4 am -o - f2fb85b9-278d-9e12-b61c-d951c71bf2f6@gmx.net | patch -p1

...

patching file drivers/ntb/test/ntb_perf.c
patch: **** malformed patch at line 23: *filep, char __user *ubuf,

Please rebase and resend.

Thanks,
Jon

Those 2 lines above should be on one line.
(i.e., they should not wrap, so set tbird's wrap length to 0)

Documentation/process/email-clients.rst has some info about
how to coerce Thunderbird into working for patches.
