[PATCH -next] habanalabs: remove set but not used variable 'ctx'

[YueHaibing]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/misc/habanalabs/device.c: In function hpriv_release:
drivers/misc/habanalabs/device.c:45:17: warning: variable ctx set but not used 
[-Wunused-but-set-variable]

It is never used since commit eb7caf84b029 ("habanalabs:
maintain a list of file private data objects")
