[U-Boot] [PATCH 14/20] mmc: Print error code for mmc_complete_init failure

[Jagan Teki]

From: Jagan Teki <jagan at amarulasolutions.com>

Print the error code for non-zero (failure case) instead
of making debug statement without any condition, this
usually gives proper clue in failure condition.

Log:
---
MMC:   FSL_SDHC: 0
mmc_init: -70, time 38
*** Warning - MMC init failed, using default environment
