Peng Jiang acea994327 vdso: Address variable shadowing in macros
Compiling the kernel with gcc12.3 W=2 results in shadowing warnings:

warning: declaration of '__pptr' shadows a previous local [-Wshadow]
  const struct { type x; } __packed *__pptr = (typeof(__pptr))(ptr);

note: in definition of macro '__put_unaligned_t'
  __pptr->x = (val);

note: in expansion of macro '__get_unaligned_t'
  __put_unaligned_t(type, __get_unaligned_t(type, src), dst);

__get_unaligned_t() and __put_unaligned_t() use a local variable named
'__pptr', which can lead to variable shadowing when these macros are used in
the same scope. This results in a -Wshadow warning during compilation.

To address this issue, rename the local variables within the macros to
ensure uniqueness.
