[PULL 06/12] linux-user: fix matching ioctl numbers in print_ioctl

[deller@kernel.org]

From: Andreas Schwab <schwab@suse.de>

target_cmd in struct IOCTLEntry is a signed int.  Make sure the ioctl cmd
argument in the syscall is converted to int when matching, so that it
works correctly with an ioctl cmd that has bit 31 set.
