Oleksandr Natalenko 25dbc20dea scsi: qedf: Do not touch __user pointer in qedf_dbg_fp_int_cmd_read() directly 
The qedf_dbg_fp_int_cmd_read() function invokes sprintf() directly on a
__user pointer, which may crash the kernel.

Avoid doing that by vmalloc()'ating a buffer for scnprintf() and then
calling simple_read_from_buffer() which does a proper copy_to_user() call.

Fixes: 61d8658b4a ("scsi: qedf: Add QLogic FastLinQ offload FCoE driver framework.")
