include/linux/notifier.h: 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 25528213 ("tags: Fix
DEFINE_PER_CPU expansions"), but this one probably wasn't noticed.
