mmc: omap: Fix NULL pointer dereference if mmc_omap_new_slot() fails
Commit b01a4f1c (mmc: omap: convert to per instance workqueue) initializes
the workqueue too late causing the following:
Unable to handle kernel NULL pointer dereference at virtual address 00000000
pgd = c0004000
[00000000] *pgd=00000000
Internal error: Oops: 5 [#1] SMP ARM

Fix this by initializing the workqueue before mmc_omap_remove_slot()
get called. Tested on n770, looks like n800 at least still has some
other issue with MMC.
