kexec: add KEXEC_FILE_NO_CMA as a legal flag

Commit 07d24902977e ("kexec: enable CMA based contiguous allocation")
introduces logic to use CMA-based allocation in kexec by default.  As part
of the changes, it introduces a kexec_file_load flag to disable the use of
CMA allocations from userspace.  However, this flag is broken since it is
missing from the list of legal flags for kexec_file_load.  kexec_file_load
returns EINVAL when attempting to use the flag.

Fix this by adding the KEXEC_FILE_NO_CMA flag to the list of legal flags
for kexec_file_load.

Without this fix, kexec_file_load syscall will failed and return
'-EINVAL' when KEXEC_FILE_NO_CMA is specified.
