This refactor the way stored keys are handled to avoid overwriting
existing keys with new keys in case of pairing failed. Main goal is
to delay update of keys (including type and encryption size) until
link is succesfully encrypted with new key (legacy STK or LE SC LTK).
To fix this properly, TK is used to store STK or LE SC LTK and updates
of keys properties are done only on successfull encryption. This makes
code less error prone since update is done only in one place in code.
Also quering SMP code for current key makes sure that correct keys is
used in case of re-pairing.

If the SDU length is bigger than the amount data received in the first

Since the MTU required by the upper layer could be much bigger than the
