Colin Ian King 72acd64df4 EVM: Fix null dereference on xattr when xattr fails to allocate ...

In the case where the allocation of xattr fails and xattr is NULL, the
error exit return path via label 'out' will dereference xattr when
kfree'ing xattr-name.  Fix this by only kfree'ing xattr->name and xattr
when xattr is non-null.

Detected by CoverityScan, CID#1469366 ("Dereference after null check")

Fixes: fa516b66a1bf ("EVM: Allow runtime modification of the set of verified xattrs")
