[ Upstream commit 9061193c4ee065d3240fde06767c2e06ec61decc ]
Driver sends update-SVID ramrod in the MFW notification path. If there is a pending ramrod, driver doesn't retry the command and storm firmware will never be updated with the SVID value. The patch adds changes to send update-svid ramrod in process context with retry/poll flags set.
