'libgomp.c/interop-hsa.c': GCN offloading only

Fix-up for commit 8d84ea28510054fbbb8a2b7441916bd75e29163f
"OpenMP, GCN: Add interop-hsa testcase", which added 'libgomp.c/interop-hsa.c'.
If nvptx offloading compilation is enabled in addition to GCN, the former ICEs:

    during RTL pass: final
    [...]/libgomp.c/interop-hsa.c: In function 'get_kernel_ptr':
    [...]/libgomp.c/interop-hsa.c:34:1: internal compiler error: RTL check: expected code 'subreg', have 'reg' in nvptx_print_operand, at config/nvptx/nvptx.cc:3082

Regardless of the issue that nvptx offloading compilation probably shouldn't
ICE, the 'asm' insert clearly is valid for GCN only.
