Fix null pointer for incremental in mdadm
when we excute mdadm --assemble, udev-md-raid-assembly.rules is triggered.
Then we stop array, we found an coredump for mdadm --incremental.func
stack are as follows:
#0 enough (level=10, raid_disks=4, layout=258, clean=1,
avail=avail@entry=0x0) at util.c:555
#1 0x0000562170c26965 in Incremental (devlist=<optimized out>,
c=<optimized out>, st=0x5621729b6dc0) at Incremental.c:514
#2 0x0000562170bfb6ff in main (argc=<optimized out>,
argv=<optimized out>) at mdadm.c:1762
func enough() use array avail,avail allocate space in func count_active,
it may not alloc space, causing a coredump.We fix this coredump.
