msm: kgsl: Add KGSL_DEV_ERR_ONCE helper macro for logging

Add KGSL_DEV_ERR_ONCE macro to kgsl_log.h, with functionality
similar to pr_err_once() but output format of dev_err(). Add logging
for deprecated code usage, to kgsl_ioctl_sharedmem_from_vmalloc()
and KGSL_USER_MEM_TYPE_ADDR switch case from kgsl_ioctl_map_user_mem()
