hid: bpf: add BPF_JIT dependency
The module does not do anything when the JIT is disabled, but instead
causes a warning:
In file included from include/linux/bpf_verifier.h:7,
from drivers/hid/bpf/hid_bpf_struct_ops.c:10:
drivers/hid/bpf/hid_bpf_struct_ops.c: In function 'hid_bpf_struct_ops_init':
include/linux/bpf.h:1853:50: error: statement with no effect [-Werror=unused-value]
1853 | #define register_bpf_struct_ops(st_ops, type) ({ (void *)(st_ops); 0; })
| ^~~~~~~~~~~~~~~~
drivers/hid/bpf/hid_bpf_struct_ops.c:305:16: note: in expansion of macro 'register_bpf_struct_ops'
305 | return register_bpf_struct_ops(&bpf_hid_bpf_ops, hid_bpf_ops);
| ^~~~~~~~~~~~~~~~~~~~~~~
Add a Kconfig dependency to only allow building the HID-BPF support
when a JIT is enabled.
