cnss2: Fix DEV SOL interrupt issue

Browse Source 
Fix misfiring of DEV SOL interrupt during enable_irq().
Ignore DEV SOL interrupt in case of device power off
as it is expected as part of off sequence.
In case of HOST triggered recovery, CNSS driver
tries to put device to RDDM first using MHI_SYS_ERR
and HOST_RESET_REQUEST if MHI_SYS_ERR fails. With
SOL enable, replace HOST_RESET_REQUEST with HOST_SOL.
