qcacld-2.0: Send user space about FW CRASHED indication

In function ol_target_failure(), if enable_self_recovery is true,
fw_indication_work_handler() will be called. Ramdump collection
will not be executed. But for no CNSS module platform, recovery flag
is neither cleaned, no any FW indication is sent to user space.
Even enable_self_recovery is false, no FW crashed indication sent
to user space.

So, add new function vos_svc_fw_crashed_ind() to send FW CRASHED IND
to user space, and clean recovery flag.
