Fix an off-by-one error in iwi_init_fw_dma(). It didn't reuse the existing
DMA memory for a firmware load if it was the exact size needed, thus in the
common case the driver was constantly free'ing and reallocating the DMA
buffer and it would eventually begin to fail. With this fix, iwi0 reuses
the same buffer the entire time and no longer fails to load the firmware
after the machine has been up for a while.
