Colin Ian King b7c56d7bfe drivers: staging: cedrus: find ctx before dereferencing it ctx 
Currently if count is an invalid value the v4l2_info message will
dereference a null ctx pointer to get the dev information. Fix
this by finding ctx first and then checking for an invalid count,
this way ctxt will be non-null hence avoiding the null pointer
dereference.

Detected by CoverityScan, CID#1475337 ("Explicit null dereferenced")

Fixes: 50e761516f ("media: platform: Add Cedrus VPU decoder driver")
