Merge branch 'two-tiny-fixes-for-btf-record'

Hou Tao says:

====================
The tiny patch set aims to fix two problems found during the development
of supporting dynptr key in hash table. Patch #1 fixes the missed
btf_record_free() when map creation fails and patch #2 fixes the missed
kfree() when there is no special field in the passed btf.
