Posix: Use simple approach to close fd

Problem: posix_release(dir) functions add the fd's into a ctx->janitor_fds
         and janitor thread closes the fd's.In brick_mux environment it is
         difficult to handle race condition in janitor threads because brick
         spawns a single janitor thread for all bricks.

Solution: Use synctask to execute posix_release(dir) functions instead of 
          using background a thread to close fds.
