When powersaving (so either wifi powersaving or deep sleep, depending on which state the firmware is in) is disabled, the way the firmware goes into host sleep is different: Usually the firmware implicitely enters host sleep on the next SLEEP event we get when we configured host sleep via HSCFG before. When powersaving is disabled though, there are no SLEEP events, the way we enter host sleep in that case is different: The firmware will send us a HS_ACT_REQ event and after that we "manually" make the firmware enter host sleep by sending it another HSCFG command with the action HS_ACTIVATE. Now waking up from host sleep appears to be different depending on whether powersaving is enabled again: When powersaving is enabled, the firmware implicitely leaves host sleep as soon as it wakes up and sends us an AWAKE event. When powersaving is disabled though, it apparently doesn't implicitely leave host sleep, but instead we need to send it a HSCFG command with the HS_CONFIGURE action and the HS_CFG_CANCEL condition. We didn't do that so far, which is why waking up from host sleep was broken when powersaving is disabled. So add some additional state to mwifiex_adapter where we keep track of whether host sleep was activated manually via HS_ACTIVATE, and if that was the case, deactivate it manually again via HS_CFG_CANCEL.
