exec: file_ram_alloc(): print error when prealloc fails
If memory allocation fails when using the -mem-prealloc command-line
option, QEMU exits without printing any error information to
the user:
# qemu [...] -m 1G -mem-prealloc -mem-path /dev/hugepages
# echo $?
1
This commit adds an error message, so that we print instead:
# qemu [...] -m 1G -mem-prealloc -mem-path /dev/hugepages
qemu: unable to map backing store for hugepages: Cannot allocate memory
