net/tls: fix encryption error checking commit a7bff11f6f9afa87c25711db8050c9b5324db0e2 upstream. bpf_exec_tx_verdict() can return negative value for copied variable. In that case this value will be pushed back to caller and the real error code will be lost. Fix it using signed type and checking for positive value.
