Joel Fernandes 56cd651e7a libcutils: ashmem: Avoid doing fd checks for ashmem calls 
Callers already verify that they are calling ashmem API on a valid fd by
calling ashmem_valid first. Lets make the fstat syscall only if the
ioctl returns -ENOTTY. This means in the regular case, only 1 syscall is
needed (ioctl) vs the current 2 (fstat+ioctl).

Some data to show improvements in reduction of vfs_getattr calls in the
kernel by 10x when doing a camera.

Test: Boot and camera CTS
