Carlos LópezandGreg Kroah-Hartman ad4b202da2 tracing/probes: fix error check in parse_btf_field() ...

[ Upstream commit e569eb3497 ]

btf_find_struct_member() might return NULL or an error via the
ERR_PTR() macro. However, its caller in parse_btf_field() only checks
for the NULL condition. Fix this by using IS_ERR() and returning the
error up the stack.
