b43: Rewrite DMA Tx status handling sanity checks
This rewrites the error handling policies in the TX status handler. It tries to be error-tolerant as in "try hard to not crash the machine". It won't recover from errors (that are bugs in the firmware or driver), because that's impossible. However, it will return a more or less useful error message and bail out. It also tries hard to use rate-limited messages to not flood the syslog in case of a failure. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
