Change dummy variable in mpih-div.c to mpi_limb_t type
* mpi/mpih-div.c (_gcry_mpih_mod_1, _gcry_mpih_divmod_1): Change dummy
variable to 'mpi_limb_t' type from 'int'.

Patch attempts to fix problem reported by Matthias Wachs:
while updating our buildbots I got another compile error:

The new x86-64 inline assembly for MPI expects outputs to be limb sized
variables (64-bit), but mpi/mpih-div.c was using 32-bit dummy variable.
Appearently this mismatch between assembly output and variable sizes does not
fail on every platform.
