brcmfmac: abort and release host after error

With commit 216b440 ("brcmfmac: Fix use after free in
brcmf_sdio_readframes()") applied, we see locking timeouts in
brcmf_sdio_watchdog_thread().

brcmfmac: brcmf_escan_timeout: timer expired
INFO: task brcmf_wdog/mmc1:621 blocked for more than 120 seconds.

"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

In addition to restarting or exiting the loop, it is also necessary to
abort the command and to release the host.
