[OFFLOAD] Update ffi_cif structure to match libffi (#128756)

Browse Source 
The ffi_cif structure defined in the wrapper header is smaller than the
actual structure in libffi which results in other structures being
overwritten when libffi is called, and finally in a segfault.

The patch updates the structure to the correct layout as specified in
ffi.h
