eabdullin f2618fd0a9 Fix build on i686: size_t vs CK_ULONG pointer incompatibility
opencryptoki-3.27.0 fails to build on i686 in %build:

  usr/lib/common/mech_openssl.c:2766:52: error: passing argument 5 of
    'EVP_PKEY_get_octet_string_param' from incompatible pointer type
    expected 'size_t *' {aka 'unsigned int *'} but argument is of type
    'CK_ULONG *' {aka 'long unsigned int *'}
  usr/lib/common/mech_openssl.c:2780:56: error: (likewise)
  usr/lib/common/mech_openssl.c:7051:36: error: passing argument 4 of
    'openssl_get_key_from_pkey' from incompatible pointer type

CK_ULONG is 'unsigned long' while size_t on ILP32 is 'unsigned int', so
only 32-bit builds break; on LP64 the types coincide. Since GCC 14
-Wincompatible-pointer-types is an error by default.

Both patches are post-v3.27.0 upstream commits (v3.27.0 was tagged
2026-05-13, the fixes landed in June/July 2026), so they are absent from
the 3.27.0-1.el10 import. RHEL 10 does not build i686 and never hit this.

Move the variable declaration of 'd_size' into the >= OpenSSL 3.0.0 block,
it is only used when building with OpenSSL >= 3.0.0.
