eth: fbnic: fix memory corruption in fbnic_tlv_attr_get_string()
This code is trying to ensure that the last byte of the buffer is a NUL
terminator. However, the problem is that attr->value[] is an array of
__le32, not char, so it zeroes out 4 bytes way beyond the end of the
buffer. Cast the buffer to char to address this.
Fixes: e5cf5107c9e4 ("eth: fbnic: Update fbnic_tlv_attr_get_string() to work like nla_strscpy()")
