libxxf86dga: fix compilation with x32 toolchain
Fix type conversion for x32. For x32 the off_t is 64bit and pointers are
32bit.
so the conversion of pointer to off_t was resulting into this error:
| XF86DGA2.c:931:24: error: cast from pointer to integer of different
size [-Werror=pointer-to-int-cast]
| cc1: some warnings being treated as errors
|
| make[2]: *** [XF86DGA2.lo] Error 1
Fixed it by typecasting pointer into unsigned long 1st and then again
typecasting unsigned long to off_t.
