Modified Files:
        src/sys/arch/x86/x86: bus_dma.c

Log Message:
modify code handling mismatch of nsegs in _bus_dmamem_alloc_range() to
a KASSERT() - plain return leaks memory, and this condition should
never trigger unless there is bug in uvm_pglistalloc(), so it seems
to be waste to check this

other ports usually simply do not check this, with exception of arm,
which does even full cleanup (checks it and calls uvm_pglistfree())
