compat_ioctl: simplify the implementation
Now that both native and compat ioctl syscalls are
in the same file, a couple of simplifications can
be made, bringing the implementation closer together:
- do_vfs_ioctl(), ioctl_preallocate(), and compat_ioctl_preallocate()
can become static, allowing the compiler to optimize better
- slightly update the coding style for consistency between
the functions.
- rather than listing each command in two switch statements
for the compat case, just call a single function that has
all the common commands.
As a side-effect, FS_IOC_RESVSP/FS_IOC_RESVSP64 are now available
to x86 compat tasks, along with FS_IOC_RESVSP_32/FS_IOC_RESVSP64_32.
This is harmless for i386 emulation, and can be considered a bugfix
for x32 emulation, which never supported these in the past.
