genirq: Initialize request_mutex if CONFIG_SPARSE_IRQ=n
commit e8458e7afa855317b14915d7b86ab3caceea7eb6 upstream.
When CONFIG_SPARSE_IRQ is disable, the request_mutex in struct irq_desc
is not initialized which causes malfunction.
Fixes: 9114014cf4e6 ("genirq: Add mutex to irq desc to serialize request/free_irq()")
