target/arm: Set correct fp flags for FLOGB when FPCR.AH = 1
Our implementation of the FLOGB insn does the operations entirely
in the helper function, without needing to use fpu functions.
This means it needs to handle all the fp status flags itself.
We aren't setting float_flag_input_denormal_used when we
use (i.e. do not flush to zero) an input denormal, which means
that FPCR.IDC isn't set when it should be for FPCR.AH=1.
We missed this when we added float_flag_input_denormal_used
and made the fpu/ code set it.
Add the missing float_raise().

target/arm: Use FPST_A64_F16 for SVE FCVTLT_hs
We should be using the F16-specific float_status for conversions from
half-precision, because halfprec inputs never set Input Denormal. If
we use the FPST_A64 fpstatus then we will incorrectly set FPCR.IDC
for input-denormals when FPCR.AH=1.
In commit e07b48995aaa we updated most of the halfprec-to-other
conversion insns to use FPST_A64_F16 as part of implementing
FEAT_AHP. However we missed the SVE FCVTLT instruction, which has a
halfprec-to-single encoding.
Correct the FPST we use for the hs variant of FCVTLT.

match queues (or number of fds). So, no matter do vhost fds come from
vhostfds or vhostfd argument. Let's use correct vhost fds for multiqueue
TAP.
To achieve this we move vhost fds parsing to separate function and call
it earlier in net_init_tap(). Then we have vhost fds available (and
already checked) for all further cases.
