scsi: isci: avoid array subscript warning
commit 5cfa2a3c7342bd0b50716c8bb32ee491af43c785 upstream.
I'm getting a new warning with gcc-7:
isci/remote_node_context.c: In function 'sci_remote_node_context_destruct':
isci/remote_node_context.c:69:16: error: array subscript is above array bounds [-Werror=array-bounds]
This is odd, since we clearly cover all values for enum
scis_sds_remote_node_context_states here. Anyway, checking for an array
overflow can't harm and it makes the warning go away.
