use_lai_streams on for BGC test?

[adrifoster]

Brief summary of bug

use_lai_streams = .true. is set for a I2000Clm50BgcCru test. This is now throwing a runtime error in my new use_lai_streams branch.

General bug information

In my new use FATES lai streams PR, I added a check to make sure use_lai_streams can only be on if use_cn = .false. or use_fates_sp = .true..

However, this now causes a runtime fail for SMS_Ld1_PS.f09_g17.I2000Clm50BgcCru.cheyenne_gnu.clm-datm_bias_correct_cruv7 test .

As this is a BGC run, I'm not sure why use_lai_streams = .true. is set in the user_nl_clm file. @ekluzek is this intended? or can I remove?
