bpf: Remove dead newline stripping from format_disasm_line()

format_disasm_line() strips trailing newlines from the disassembly it
stores, as diag_print_insn_context() adds its own. Since
commit 483a1bb0b6cf8 ("bpf: Do not print a newline after disassembly in
bpf_verbose_insn()"), print_bpf_insn() does not emit one, so there is
nothing left to strip.

The strnlen() resync of the seq_buf length only existed so the loop
could index the buffer safely after an overflow, and the second
termination only restored the NUL that seq_buf_pop() does not write.
Remove all of it, keeping a single seq_buf_terminate().

Build tested ARCH=x86_64 defconfig with GCC 16.2.0 and
CONFIG_BPF_SYSCALL=y.
