mtd: spear_smi: add NULL check on devm_kzalloc() return value
Check return value from call to devm_kzalloc()
in order to prevent a NULL pointer dereference.
This issue was detected using Coccinelle and the following semantic patch:
@@
expression x;
identifier fld;
@@
* x = devm_kzalloc(...);
... when != x == NULL
x->fld
