EVM: prevent array underflow in evm_write_xattrs()
If the user sets xattr->name[0] to NUL then we would read one character
before the start of the array. This bug seems harmless as far as I can
see but perhaps it would trigger a warning in KASAN.
Fixes: fa516b66a1bf ("EVM: Allow runtime modification of the set of verified xattrs")
