RCfailsafe

[jiezhi320]

 Recently, I build a quad X with aq m4. when I test fail safe function(ascent ,home then land)  I find A strange phenomenon :when the plan goes to home alt, it goes up All of a sudden(it should be going down ).  I test failsafe function for 5 times, this phenomenon appear 2 times.  

Then I download the code and view, I find when navSetHomeCurrent , there is no filter. May be an illegal alt value be set to current alt.
I think when set navSetHomeCurrent there should have a filer.
