[LU-462] lut_client_alloc/free() shouldn't be called for self_export

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.2.0

Description

There are two bad effects with obd_self_export passing to lut_client_alloc/free. First, it is just not needed to allocate client data for it, second, this can cause assertion in lut_client_free() if lut_init() wasn't called due to failed mdt_init0().

Fix could be just check for exp == exp->exp_obd->obd_self_export in mdt/obdfilter. Alternatively that can be done inside lut_client_alloc/free but I like to keep them generic
