[PATCH v2 1/2] staging: r8188eu: Use sizeof dereferenced pointer in kzalloc()

checkpatch.pl emits the following warning:

CHECK: Prefer kzalloc(sizeof(*pcmd)...) over kzalloc(sizeof(struct cmd_obj)...)
+ pcmd = kzalloc(sizeof(struct cmd_obj), GFP_KERNEL);

CHECK: Prefer kzalloc(sizeof(*psetkeyparm)...) over kzalloc(sizeof(struct setkey_parm)...)
+ psetkeyparm = kzalloc(sizeof(struct setkey_parm), GFP_KERNEL).

According to the above "CHECK[S]", use the preferred style in the two kzalloc()
of rtw_set_key().
