f2fs: fix to update injection attrs according to fault_option

When we update inject type via sysfs, it shows wrong rate value as
below, there is a same problem when we update inject rate, fix it.

Before:
F2FS-fs (vdd): build fault injection attr: rate: 0, type: 0xffff
F2FS-fs (vdd): build fault injection attr: rate: 1, type: 0x0

After:
F2FS-fs (vdd): build fault injection type: 0x1
F2FS-fs (vdd): build fault injection rate: 1

Meanwhile, let's avoid turning on all fault types when we enable fault
injection via fault_injection mount option, it will lead to shutdown
filesystem or fail the mount() easily.

mount -o fault_injection=4 /dev/vdd /mnt/f2fs
F2FS-fs (vdd): build fault injection attr: rate: 4, type: 0x7fffff
F2FS-fs (vdd): inject kmalloc in f2fs_kmalloc of f2fs_fill_super+0xbdf/0x27c0
