rS326702: Handle read-only mbufs in iflib ether pad function
Summary

If ethernet padding is enabled, and a read-only mbuf is passed,
it would modify the mbuf using m_append(). Instead, call m_dup() and
append to the new packet.

Test Plan

Validate with A0 hardware and patches discussed in D13269 and D13324.
