net/mlx5: E-Switch, return error if encap isn't supported

Browse Source 
[ Upstream commit c4c3176739dfa6efcc5b1d1de4b3fd2b51b048c7 ]

On regular ConnectX HCAs getting encap mode isn't supported when the
E-Switch is in NONE mode. Current code would return no error code when
trying to get encap mode in such case which is wrong.

Fix by returning error value to indicate failure to caller in such case.
