[Intel-wired-lan] [net-next 07/13] ice: use 'int err' instead of 'int status'

[Jacob Keller <jacob.e.keller@intel.com>]

The ice_ptp_hw.c file introduced a bunch of uses of "int status" instead
of the more traditional "int err" or "int ret". These are actually
traditional Linux error codes (as opposed to the ice_status enumeration
values), so lets convert them all now to use "int err" for clarity. This
is likely an artifact of refactoring this code to minimize the use of
ice_status enumeration in preparation for removing it. We want to avoid
adding any new usages of the status enum.
