ALSA: compress_offload: tighten ioctl command number checks
The snd_compr_ioctl() ignores the upper 24 bits of the ioctl command
number and only compares the number of the ioctl command, which can
cause unintended behavior if an application tries to use an unsupprted
command that happens to have the same _IOC_NR() value.
Remove the truncation to the low bits and compare the entire ioctl
command code like every other driver does.
