imgact_elf: do not relock the text vnode if possible.

We unlock the vnode around malloc(M_WAITOK), to make it possible for
pagedaemon to flush vnode pages for us.  Instead of doing it
unconditionally, first try M_NOWAIT allocation, which typically
succeed.  Only on failure, unlock the vnode and retry with M_WAITOK.
