scsi: qla2xxx: Fix memory leak in qla2x00_probe_one()

There is a memory leak reported by kmemleak:

  unreferenced object 0xffffc900003f0000 (size 12288):
    comm "modprobe", pid 19117, jiffies 4299751452 (age 42490.264s)
    hex dump (first 32 bytes):

      [<0000000001906886>] __vmalloc_node+0xbd/0x150

      [<00000000641ccc04>] local_pci_probe+0xeb/0x1a0

The root cause is traced to an error-handling path in qla2x00_probe_one()
when the adapter "base_vha" initialize failed. The fab_scan_rp "scan.l" is
used to record the port information and it is allocated in
qla2x00_create_host(). However, it is not released in the error handling
path "probe_failed".

Fix this by freeing the memory of "scan.l" when an error occurs in the
adapter initialization process.
