Miaoqian Lin 5d5f08fd0c xtensa: simdisk: add input size check in proc_write_simdisk 
A malicious user could pass an arbitrarily bad value
to memdup_user_nul(), potentially causing kernel crash.

This follows the same pattern as commit ee76746387
("netdevsim: prevent bad user input in nsim_dev_health_break_write()")

Fixes: b6c7e873da ("xtensa: ISS: add host file-based simulated disk")
Fixes: 16e5c1fc36 ("convert a bunch of open-coded instances of memdup_user_nul()")
