genirq: Use cpumask_available() for check of cpumask variable
This fixes the following clang warning when CONFIG_CPUMASK_OFFSTACK=n: kernel/irq/manage.c:839:28: error: address of array 'desc->irq_common_data.affinity' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion] Signed-off-by: Matthias Kaehlcke <mka@chromium.org> Cc: Grant Grundler <grundler@chromium.org> Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Greg Hackmann <ghackmann@google.com> Cc: Michael Davidson <md@google.com> Cc: Andrew Morton <akpm@linux-foundation.org> Link: http://lkml.kernel.org/r/20170412182030.83657-2-mka@chromium.org Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
