bpf: Use BPF_CALL_IMM macro consistently in bpf_do_misc_fixups

Browse source

In bpf_do_misc_fixups(), the conversion from a function address to a
BPF immediate value is handled using the BPF_CALL_IMM macro inside the
'patch_map_ops_generic' label block. However, immediately following it
in the 'patch_call_imm' label block, the immediate value is calculated
manually by subtracting __bpf_call_base from fn->func.

Inspired by KaFai Wan's review comments on fixing helper call offsets,
use the BPF_CALL_IMM macro in 'patch_call_imm' as well to clean this up.
This removes the redundant manual pointer arithmetic and ensures coding
style consistency across adjacent label blocks within the same function.
