mtd: physmap: fix NULL pointer dereference in error path
commit e480814f138cd5d78a8efe397756ba6b6518fdb6 ("[MTD] [MAPS] physmap:
fix wrong free and del_mtd_{partition,device}") introduces a NULL pointer
dereference in physmap_flash_remove when called from the error path in
physmap_flash_probe (if map_probe failed).
Call del_mtd_{partition,device} only if info->cmtd was not NULL.
