[XEN PATCH v2 2/4] x86/mm: remove variable to avoid shadowing

[Nicola Vetrini <nicola.vetrini@xxxxxxxxxxx>]

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.

Both variables were last introduced by commit
d4f699a0df6cea907c1de5c277500b98c0729685.

No functional changes.

Change in v2:
- removed the innermost p2mt instead of renaming it.
