bnxt_en: correct offset handling for IPv6 destination address

[ Upstream commit 3d3aa94 ]

In bnxt_tc_parse_pedit(), the code incorrectly writes IPv6
destination values to the source address field (saddr) when
processing pedit offsets within the destination address range.

This patch corrects the assignment to use daddr instead of saddr,
ensuring that pedit operations on IPv6 destination addresses are
applied correctly.
