unqlite.c: unsigned differences compared to 0 #154

In the following lines (36039, 36136, 36173 respectively), the difference of two unsigned integers is compared to 0. However, since the difference of two unsigned integers can never be less than 0, this suggests that the comparison might mask a bug.

if( SyBlobLength(&pDev->sBuffer) - pDev->nOfft > 0 ){ if( SyBlobLength(&pDev->sBuffer) - pDev->nOfft > 0 ){ if( SyBlobLength(&pDev->sBuffer) - pDev->nOfft > 0 ){
