Subject: [PATCH] mpt3sas:Make sure mpt3sas adapter has been reset in scsih_resume

This fixes the issue in the function scih_resume that we assume
that the mpt3sas adapter has been reset properly with a call to
mpt3sas_base_hard_reset_handler by checking if this function
call returns a error code and exit adpater resume prematurely
