accel/amdxdna: Use int instead of u32 to store error codes
Change the 'ret' variable from u32 to int to store -EINVAL. Storing the
negative error codes in unsigned type, doesn't cause an issue at runtime
but it's ugly as pants.
Additionally, assigning -EINVAL to u32 ret (i.e., u32 ret = -EINVAL) may
trigger a GCC warning when the -Wsign-conversion flag is enabled.
Fixes: aac243092b70 ("accel/amdxdna: Add command execution")
