Description of problem:

mkinitrd does not sort the scsi_hostadapter in the /etc/modprobe.conf file
correctly if you have more than 10 entries. Overall this might not sound like
that big an issue but it is if you need certain scsi_hostadapter loaded before

Version-Release number of selected component (if applicable):

How reproducible:
Always. Just have scsi_hostadapter 1-10 (plus the one with no number) in the
modprobe.conf file and run mkinitrd. Check the results, by taking a part the
.img file and looking at the init file. It will show that driver specified by 
scsi_hostadapter10 is loaded third. 

A simpler test is to use the command that mkinitrd uses to sort these entries,

grep "alias[[:space:]]\+scsi_hostadapter" /etc/modprobe.conf | grep -v '^[     
  ]*#' | LC_ALL=C sort -u | awk '{ print $3 }'

The resulting list will show that scsi_hostadapter10 is in the third position.

Steps to Reproduce:
1. Create 11 valid scsi_hostadapter entries (1-10) in the /etc/modprobe.conf
2. Run mkinitrd
3. Examine the resulting .img file (unzip it, cpio -idumv < <file>). Look
at init file. Driver that is identified by scsi_hostadapter10 will be in 
the third position.

Actual results:

Expected results:
