[PATCH] scsi: bnx2fc: Use kmalloc_array() for array allocations

[Can Peng]

Documentation/process/deprecated.rst discourages open-coded arithmetic
in allocator arguments and recommends using the 2-factor allocator forms.

The unsolicited completion path allocates num_rq buffers of
BNX2FC_RQ_BUF_SZ bytes, and task_ctx_dma is an array of task_ctx_arr_sz
dma_addr_t entries. Use kmalloc_array() for both allocations.
