[PATCH] docs/bpf: Fix a typo in verifier.rst

[linsyking]

In verifier.rst, there is a typo in section 'Register parentage chains'.
Caller saved registers are r0-r5, callee saved registers are r6-r9.

Here by context it means callee saved registers rather than caller saved
registers. This may confuse users.

Thanks for the patch, but I suspect "linsyking" is not your full name.
The kernel patch rules are strict. Please use your full first/last name
as an author and in signed-off-by.

Thanks

In verifier.rst, there is a typo in section 'Register parentage chains'.
Caller saved registers are r0-r5, callee saved registers are r6-r9.

Here by context it means callee saved registers rather than caller saved
registers. This may confuse users.
