Sean Anderson 4f45b2c352 semihosting: Fix GDB File-I/O FLEN 
fstat returns 0 on success and -1 on error. Since we have already
checked for error, ret must be zero. Therefore, any call to fstat on a
non-empty file will return -1/EOVERFLOW.

Restore the original logic that just did a byteswap. I don't really know
what the intention of the fixed commit was.
