irqchip/gic-v3: Fix OF_BAD_ADDR error handling
When building with extra warnings enabled, clang points out a mistake in the error handling: drivers/irqchip/irq-gic-v3-mbi.c:306:21: error: result of comparison of constant 18446744073709551615 with expression of type 'phys_addr_t' (aka 'unsigned int') is always false [-Werror,-Wtautological-constant-out-of-range-compare] if (mbi_phys_base == OF_BAD_ADDR) { Truncate the constant to the same type as the variable it gets compared to, to shut make the check work and void the warning.
