Subject: [PATCH 4.19 566/639] bnxt_en: Increase timeout for HWRM_DBG_COREDUMP_XX commands

From: Vasundhara Volam <vasundhara-v.volam@...adcom.com>

[ Upstream commit 57a8730b1f7a0be7bf8a0a0bb665329074ba764f ]

Firmware coredump messages take much longer than standard messages,
so increase the timeout accordingly.

Fixes: 6c5657d085ae ("bnxt_en: Add support for ethtool get dump.")
