bcmdhd: Ignore the Coredump generation for the continuous packet drop with SKIP_COREDUMP_PKTDROP_RXHC
Google requested to stop the coredump generation for the shipping Phone image which doesn't generate the coredump even if DHD triggers the dongle trap.
Make the SKIP_COREDUMP_PKTDROP_RXHC flag to control the coredump generate.
Bug: 274302570
Test: Regression test
