Fix two places where the wrong type or conversion of little-endian
types to fix the following sparse warnings:
drivers/mmc/host/cqhci-core.c:487:15: warning: incorrect type in assignment (different base types)
drivers/mmc/host/cqhci-core.c:487:15: expected restricted __le32 [usertype]
drivers/mmc/host/cqhci-core.c:487:15: got int
drivers/mmc/host/cqhci-core.c:566:19: warning: incorrect type in assignment (different base types)
drivers/mmc/host/cqhci-core.c:566:19: expected unsigned long long [usertype] *task_desc
drivers/mmc/host/cqhci-core.c:566:19: got restricted __le64 [usertype] *
