[PATCH 6.7 111/713] net: test: Fix printf format specifier in skb_segment kunit test

[ Upstream commit ff3b96f2c9e5c24fca12239cd519a8a18569e687 ]

KUNIT_FAIL() accepts a printf-style format string, but previously did
not let gcc validate it with the __printf() attribute. The use of %lld
for the result of PTR_ERR() is not correct.

Instead, use %pe and pass the actual error pointer. printk() will format
it correctly (and give a symbolic name rather than a number if
available, which should make the output more readable, too).
