[Error Msg] ++ set_initrd ++ initrd=initrd ++ cat <<< hang here

[Root Cause] Function set_initrd() have follow line: cat $initrds > $initrd

when $initrds is null, the script will hang when execute cat command.

[how] before: firstly, `cat $initrds > $initrd`, secondly, `[ -n "$initrds" ] || exit` after: directly use `[ -n "$initrds" ] && cat $initrds > initrd || exit`

[why] 1. before execute cat command, check wether initrds is null. 2. initrd is a brief file name, it can be used directly, so remove $initrd, just us initrd. 3. set_initrd() is unnecessary, so remove.
