spl: fix calling "spl export .." more than once

Browse Source 
running "spl export ..." more than once fails with:

Trying to execute a command out of order
Trying to execute a command out of order
Trying to execute a command out of order
Trying to execute a command out of order
Trying to execute a command out of order
Trying to execute a command out of order
ERROR prep subcommand failed!
Subcommand failed

reason is commmit:
35fc84fa1f: Refactor the bootm command to reduce code duplication

It used "state != BOOTM_STATE_START" but state is a bitfield, so
check if the bit BOOTM_STATE_START is not set. With this fix,
"spl export ..." can called more than once ...
