ITS#7453 Fix reset of MDB_NOSYNC/MDB_NOMETASYNC.

mdb_env_open() with these flags did not open a synchronizing
file descriptor. Thus disabling them later did not work.

Renumber MDB_NOSUBDIR. Check mdb_env_open() flags.
...
MDB_NOSUBDIR was == MDB_REVERSEKEY. That affected the freelist:
Env flags are stored in mm_flags alias mm_dbs[FREE_DBI].md_flags.
It stays a persistent flag, in case mdb_env_open someday wants
to pick/verify which lockfile to use with the datafile.
Catch bad flags so they will no longer make it into the data file.
