Dan Rosenberg f40fe91c33 ARM: 6891/1: prevent heap corruption in OABI semtimedop
commit 0f22072ab5 upstream.

When CONFIG_OABI_COMPAT is set, the wrapper for semtimedop does not
bound the nsops argument.  A sufficiently large value will cause an
integer overflow in allocation size, followed by copying too much data
into the allocated buffer.  Fix this by restricting nsops to SEMOPM.
Untested.
