CLEANUP: stconn: remove the new unneeded SE_FL_APP_MASK

The only two places where it was used was to carefully preserve the
SE_FL_WILL_CONSUME flag (since others are irrelevant there and the
previous RXBLK* flags moved to the stconn). Now that the flag is
cleared by default there's no need to re-created a fresh new one
when replacing the descriptor, so we can eliminate that remaining
trick.
