If qcom_smem_get or qcom_smem_alloc return -EPROBE_DEFER, let the caller
the caller handle it, instead of treating it as an error.

v1:
- TODO: Reading qcom_smsm_probe, I noticed memory leaks in error paths:
smsm, smsm->entries, etc. are allocated (with devm_kzalloc), but not
freed when the function returns early. This should be addressed at
some point (in a separate patch).
