kernel/SRCU: Fix ctags

ctags indexing ("make tags" command) throws this warning:

ctags: Warning: include/linux/notifier.h:125:
null expansion of name pattern "\1"

This is the result of DEFINE_PER_CPU() macro expansion. Fix that by getting rid of line break.

Similar fix was already done in commit 25528213fe9f ("tags: Fix DEFINE_PER_CPU expansions"), but this one probably wasn't noticed.
