srcu: Fix warning to permit SRCU-fast readers in NMI handlers
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.
