cxgb4: use unaligned conversion for fetching timestamp
[ Upstream commit 589b1c9c166dce120e27b32a83a78f55464a7ef9 ]
Use get_unaligned_be64() to fetch the timestamp needed for ns_to_ktime()
conversion.
Fixes following sparse warning:
sge.c:3282:43: warning: cast to restricted __be64
Fixes: a456950445a0 ("cxgb4: time stamping interface for PTP")
