scsi: megaraid_sas: reduce size of fusion_context and use vmalloc if kmalloc fails
Currently fusion context has fixed array load_balance_info. Use dynamic
allocation. In few places, driver do not want physically contigious
memory. Attempt to use vmalloc if physical contiguous memory is not
available.
