ARM: 7216/1: mmc: mmci: Do not release spinlock in request_end
The patch "mmc: core: move ->request() call from atomic context",
is the reason to why this change is possible. This simplifies the
error handling code execution path quite a lot and potentially also
fixes some error handling hang problems.
