scsi: sd: reject invalid pr_read_keys() num_keys values
The pr_read_keys() interface has a u32 num_keys parameter. The SCSI
PERSISTENT RESERVE IN command has a maximum READ KEYS service action
size of 65536 bytes. Reject num_keys values that are too large to fit
into the SCSI command.
This will become important when pr_read_keys() is exposed to untrusted
userspace via an <linux/pr.h> ioctl.
