staging/et131x: fix et131x_rx_dma_disable halt_status usage
Commit 1bd751c1abc1029e8a0ae63ef4f19357c735a2a3
("Staging: et131x: Clean up rxdma_csr") changed csr from bitfield to
u32, but failed to convert 2 uses of halt_status bit. It did:
- if (csr.bits.halt_status != 1)
+ if ((csr & 0x00020000) != 1)
which is wrong, because second version is always true.
Fix it.
