[PATCH] kunit: Documentation: Fix a kernel-doc reference

[David Gow <davidgow@google.com>]

When building the KUnit documentation, the reference to
kunit_test_suites in the kunit_test_init_section_suites kernel-doc
comment gives an error:
Documentation/dev-tools/kunit/api/test:9: ./include/kunit/test.h:323: WARNING: Inline interpreted text or phrase reference start-string without end-string.

This is because the reference is mixing two function reference styles:
adding an '&' to the front, and "()" to the end. The latter is neater,
so get rid of the '&'.

Fixes: 9bf2eed995f9 ("kunit: add support for kunit_suites that reference init code")
Signed-off-by: David Gow <davidgow@google.com>

(As a KUnit patch, we'll accept this via the KUnit tree.)
