[dev][sdmmc] Fix missized buffer and missing returns

Fix two problems:
1) The sdmmc_query function was reporting the wrong struct size, causing
transaction structs to be incorrectly sized.  With a small change to the
struct, this could easily turn into a buffer overrun when accessing the
transaction structure.
2) Two early-return cases were missing returns, potentially causing two
completion callback invocations in those cases.
