From: Arnd Bergmann <arnd@arndb.de>
When debugging is disabled, the ASSERT() is left out and
the 'log' variable becomes unused:
fs/xfs/xfs_log.c:1111:16: error: unused variable 'log' [-Werror,-Wunused-variable]
Remove the variable declaration and open-code it inside
of the assertion.
Fixes: 303591a0a947 ("xfs: cover the log during log quiesce")

I sent basically the same patch[1] about a week ago, but either one is
fine with me:
