Subject: [PATCH 16/19] remoteproc: q6v5_wcss: change ssr name for ipq6018 wifi
 subsystem

On IPQ6018 this string ends up being sent to RPM when remoteproc stops
(on crash or rmmod ath11k). "q6wcss" is not a valid name (not found by
`strings` in rpm.mbn), so this causes RPM do 'something' (presumably crash)
causing a system reboot followed by hang in XBL, with no WDT running.
Let's change ssr_name to a more sensible 'wcnss', that does not cause such
issues.
