Kefeng Wang 82e1fb4d37 genirq: Initialize request_mutex if CONFIG_SPARSE_IRQ=n ...

commit e8458e7afa upstream.

When CONFIG_SPARSE_IRQ is disable, the request_mutex in struct irq_desc
is not initialized which causes malfunction.

Fixes: 9114014cf4 ("genirq: Add mutex to irq desc to serialize request/free_irq()")
