binder: Fix log spam caused by interrupted waits

Being interrupted by a signal during binder ioctls is not unusual.
Commit 218225c05beaf02320f05a9b3b7041e27a0684f7 changed the interrupted
ioctl return code from ERESTARTSYS to EINTR, but the error logging check
was never updated:

[  352.090265] binder: 6534:6552 ioctl c0306201 7a0f9fea10 returned -4
[  352.090393] binder: 6534:7670 ioctl c0306201 7a6489da10 returned -4
[  352.090432] binder: 6534:9501 ioctl c0306201 7a61377a10 returned -4

Update the return code to fix the log spam.
