Fixed issue with LOCK TABLE + ALTER TABLE ENABLE KEYS + SHOW commands.

sql/sql_table.cc:
  Remove version protection from share when repair has been done.
  Without this one can't run SHOW commands on the table if it was locked until it's unlocked.
sql/table.h:
  Allow one to remove version protection with allow_access_to_protected_table()
