No, ESP is not a normal extension header, it terminates parse.
So, ipv6_skip_headers cannot skip it.
BTW the same is with netfilter. I do not see how are you going to use it. :-)

I am afraid this will simply break the function.

This may be right even not depending on this issue. Goals are different:
the function in exthdrs.c does the best efforts to guess what protocol
is, the function in netfilter should be paranoid.
