MDEV-26811: Assertion "log_sys->n_pending_flushes == 1" fails
In commit 1cb218c37cc3fe01a1ff2fe9b1cbfb591e90d5ce (MDEV-26450)
we introduced the function log_write_and_flush(), which may
compete with log_checkpoint() invoking log_write_flush_to_disk_low()
from another thread.
The assertion n_pending_flushes==1 is too strict.
There is no possibility of a race condition here, because
fil_flush() is protected by fil_system->mutex and the
rest will be protected by log_sys->mutex.
log_write_flush_to_disk_low(), log_write_and_flush():
Relax the assertions to test for a nonzero count.
