kbuild: Drop -Wdeclaration-after-statement

Browse source 
commit b5ec6fd286dfa466f64cb0e56ed768092d0342ae upstream.

With the advent on scope-based resource management it comes really
tedious to abide by the contraints of -Wdeclaration-after-statement.

It will still be recommeneded to place declarations at the start of a
scope where possible, but it will no longer be enforced.
