linux-gen: shm: do not print map error
map error just spams output screen and it's impossible
to see anything in the log. No need this extra debug
print. It's ok if memory can not be allocated in HP and
reservation fails to normal pages.

linux-gen: do not use huge pages for internal allocations
Some linux-generic internal shared memory allocations have
to be in normal pages due to small required data. Relaying
on odp_sys_huge_page_size() is not really correct, because
call returns default huge page size. But default huge page
size is definned in kernel boot parameter as:
default_hugepagesz=1G hugepagesz=1G hugepages=2
So in that case for small allocation linux-gen will create 1GB
huge page. This patch introduces internal flag to shm funtion
to allocate hp.
This patch remains allowing changes on top of it:
For now pools are in huge page. And for apps with small pool it's
big overhead of unused memory. We should take into account
odp_sys_huge_page_size_all() call and found best sized huge pages.
