[U-Boot] [PATCH 7/9] mx6qarm2: Return error if the SDHC port index is invalid

[Fabio Estevam]

When the SDHC port number index is invalid we should return an error code 
immediately.

Currently we return 'status', which has a value of zero, causing  
board_mmc_init() to incorrectly return sucess.

Fix this by returning -EINVAL instead.
