scsi: pm8001: Fix abort all task initialization
Details

In the Linux kernel, the following vulnerability has been resolved:

scsi: pm8001: Fix abort all task initialization

In pm80xxsendabortall(), the nelem field of the ccb used is not initialized to 0. This missing initialization sometimes lead to the task completion path seeing the ccb with a non-zero nelem resulting in the execution of invalid dmaunmapsg() calls in pm8001ccbtaskfree(), causing a crash such as:

Avoid this issue by always initializing the ccb nelem field to 0 in pm8001sendabortall(), pm8001sendreadlog() and pm80xxsendabortall().
