dm flakey: return -EINVAL on interval bounds error in flakey_ctr()

Browse source 
commit bff7e067ee518f9ed7e1cbc63e4c9e01670d0b71 upstream.

Fix to return error code -EINVAL instead of 0, as is done elsewhere in
this function.

Fixes: e80d1c805a ("dm: do not override error code returned from dm_get_device()")
