Subject: [PATCH] Fix missing page index argument in reentrant write lock
 warning

PAGE_LOCKED_TIMES is "Page [{}] had been locked {} times.", but only the
write hold count was passed to the logger. SLF4J filled the first
placeholder with the count and printed the second one literally, so the
warning reported the hold count as the page index and never showed the
count itself.

Pass page.getPageIndex() as the first argument, matching the neighbouring
REENTRANT_WRITE_LOCKS_DETAIL call in the same method.
