PositionManager:_reversePosition() calculates the notional to reverse but could just use the exchangedQuote

Low/InfoNftperp Matching Engine audit·Three Sigma·NFT perpetuals·29th January, 20243S-NFTPerp-N01

Description

PositionManager:_reversePosition() reduces the notional by the amount required to close the previous position, fetching the value using the getters before.

However, it could use closeResponse.exchangedQuote() instead, which does the same calculations.
