scsi: megaraid_sas: Protect megasas_get_ctrl_info() in megasas_resume()

Browse source

Protect the megasas_get_ctrl_info() call in megasas_resume() with
instance->reset_mutex using scoped_guard().

megasas_get_ctrl_info() may release and reacquire instance->reset_mutex.
Hence, calling this function without holding instance->reset_mutex is not
safe.
