bnxt_en: Make PTP timestamp HWRM more silent
commit 056bce63c469 ("bnxt_en: Make PTP TX timestamp HWRM query silent")
changed a netdev_err() to netdev_WARN_ONCE().
netdev_WARN_ONCE() is it generates a kernel WARNING, which is bad, for
the following reasons:
* You do not a kernel warning if the firmware queries are late
* In busy networks, timestamp query failures fairly regularly
* A WARNING message doesn't bring much value, since the code path
is clear.
(This was discussed in-depth in [1])
Transform the netdev_WARN_ONCE() into a netdev_warn_once(), and print a
more well-behaved message, instead of a full WARN().
