ir: fix allocation of memory without size check issue [1/1]

PD#SWPL-11248

Problem:
When handling the set attribute IOCTL REMOTE_IOC_SET_KEY_NUMBER, the driver
does not limit the size of allocation with kzalloc.

Solution:
Limit the size of alllcation range, if given a value out of range, set
update flag to false and do nothing in kzalloc stage.

Verify:
