illumos gate

From Daniil Lunev

Problem is that there is the race condition between libshare and smf. Libshare starts smb service, but it can go forward with sharing before smf actually begins work with service. cr3848 fixes this race and eliminates errors masking. It will wait for server up to 15 second. If server gets online during this 15 second, then everything is ok. If not, then we propogate error to the upper level. Having this error returned, upper level sets up return code with error, but tries to share other datasets (until datasets is over, service gets online, service gets maintained (one of that)).
