mtd: parsers: qcom: Fix error condition

qcom_smem_get() does not return NULL, and even if it did, the NULL
condition is usually not an error but a success condition and should
not trigger an error trace.

Let's replace IS_ERR_OR_NULL() by IS_ERR().

This fixes the following smatch warning:
drivers/mtd/parsers/qcomsmempart.c:109 parse_qcomsmem_part() warn: passing zero to 'PTR_ERR'
