irqchip/gic-v3-mbi: Fix uninitialized mbi_lock
[ Upstream commit c530bb8a726a37811e9fb5d68cd6b5408173b545 ]
The mbi_lock mutex is left uninitialized, so let's use DEFINE_MUTEX
to initialize it statically.
Fixes: 505287525c24d ("irqchip/gic-v3: Add support for Message Based Interrupts as an MSI controller")
