cxl/test: Fix __fortify_panic
Fix a runtime assertion in setup_xor_mapping(). Fortify complains that it
is potentially overflowing the xormaps array per __counted_by(nr_maps).
Quiet the false positive by initializing @nr_maps earlier.
memcpy: detected buffer overflow: 32 byte write of buffer size 0
WARNING: lib/string_helpers.c:1036 at __fortify_report+0x4d/0xa0, CPU#8: modprobe/2728
Call Trace:
__fortify_panic+0xd/0xf

[ dj: Fixed up @nr_entries to @nr_maps in commit log. ]
