Removed the redundant usage of layer.

Since DBAL is database abstraction layer, and is defined in the document as such, to me it reads funny to have it as database abstraction layer layer. It sounds nitpicky, I know, but I find it an easier read this way. Also, the possessive DBAL stuck out ("DBAL's layer") as the DBAL doesn't own a layer, it is the layer.
Shorten the = to match the length of the text.
Removed the possession from Doctrine.
One more again. I could have sworn I had them lined up.
minor #4375 Removed the redundant usage of layer. (micheal)

This PR was submitted for the 2.5 branch but it was merged into the 2.3 branch instead (closes #4375).

It sounds nitpicky, I know, but I find it an easier read this way. Also, the possessive DBAL stuck out ("DBAL's layer") as the DBAL doesn't own a layer, it is the layer whereas Doctrine does own the layer and is properly defined in the header.

Inline condition removed for easier reading

Previous inline condition would cause confusion or trigger notifications in IDE (Netbeans,...)
