SRCU-fast is designed to be used in NMI handlers, even going so far as to use atomic operations for architectures supporting NMIs but not providing NMI-safe per-CPU atomic operations. However, the WARN_ON_ONCE() in __srcu_check_read_flavor() complains if SRCU-fast is used in an NMI handler. This commit therefore modifies that WARN_ON_ONCE() to avoid such complaints.
