scsi: qedf: fix LTO-enabled build 

The prototype for qedf_dbg_fops/qedf_debugfs_ops doesn't match the definition,
which causes the final link to fail with link-time optimizations:

drivers/scsi/qedf/qedf_main.c:34: error: type of 'qedf_dbg_fops' does not match original declaration [-Werror=lto-type-mismatch]
 extern struct file_operations qedf_dbg_fops;

drivers/scsi/qedf/qedf_debugfs.c:443: note: 'qedf_dbg_fops' was previously declared here
 const struct file_operations qedf_dbg_fops[] = {

drivers/scsi/qedf/qedf_main.c:33: error: type of 'qedf_debugfs_ops' does not match original declaration [-Werror=lto-type-mismatch]
 extern struct qedf_debugfs_ops qedf_debugfs_ops;

drivers/scsi/qedf/qedf_debugfs.c:102: note: 'qedf_debugfs_ops' was previously declared here
 struct qedf_debugfs_ops qedf_debugfs_ops[] = {

This corrects the prototype and moves it into a shared header file where it
belongs. The file operations can also be marked 'const' like the
qedf_debugfs_ops.
