[PATCH V1] mtd : nand : denali :- No need of devm functions

[Arvind Yadav]

In function denali_init, the memory allocated for denali->buf.buf
is live within the function only. After the allocation it is
immediately freed with devm_kfree. There is no need to allocate
memory for denali->buf.buf with devm function so replace
devm_kzalloc with kzalloc and devm_kfree with kfree.
