octeontx2-af: Fix memory leak of object buf
[ Upstream commit 9e0a537d06fc36861e4f78d0a7df1fe2b3592714 ]
Currently the error return path when lfs fails to allocate is not free'ing
the memory allocated to buf. Fix this by adding the missing kfree.
Addresses-Coverity: ("Resource leak")
Fixes: f7884097141b ("octeontx2-af: Formatting debugfs entry rsrc_alloc.")
