irqchip/loongson-pch-msi: Use bitmap_zalloc() to allocate bitmap
Currently we use bitmap_alloc() to allocate msi bitmap which should be
initialized with zero. This is obviously wrong but it works because msi
can fallback to legacy interrupt mode. So use bitmap_zalloc() instead.
Fixes: 632dcc2c75ef6de3272aa ("irqchip: Add Loongson PCH MSI controller")
