cxl/fwctl: Fix __fortify_panic
Fix a runtime assertion in cxlctl_get_supported_features(). Fortify
complains that it is potentially overflowing the entries array per
__counted_by_le(num_entries). Quiet the false positive by initializing
@num_entries earlier.
memcpy: detected buffer overflow: 48 byte write of buffer size 0
WARNING: lib/string_helpers.c:1036 at __fortify_report+0x4d/0xa0, CPU#7: fwctl/1398
RIP: 0010:__fortify_report+0x50/0xa0
Call Trace:
__fortify_panic+0xd/0xf
cxlctl_get_supported_features.cold+0x23/0x35 [cxl_core]
Fixes: 4d1c09cef2c2 ("cxl: Add support for fwctl RPC command to enable CXL feature commands")
