x86/mm: remove variable to avoid shadowing

The local variable 'p2mt' shadows a declaration of the same variable
in the enclosing scope, but removing the inner declaration
does not alter the semantics ('p2mt' is an output for the get_gfn
call later on) and this resolves a violation of
MISRA C:2012 Rule 5.3.

No functional changes.
